3.0Fixed disk subsystem description

3.1Control Electronics

The drive is electronically controlled by a microprocessor, several logic modules, digital/analog modules, and various drivers and receivers. The control electronics performs the following major functions:

•Controls and interprets all interface signals between the host controller and the drive.

•Controls read write accessing of the disk media, including defect management and error recovery.

•Controls starting, stopping, and monitoring of the spindle.

•Conducts a power-up sequence and calibrates the servo.

•Analyzes servo signals to provide closed loop control. These include position error signal and estimated velocity.

•Monitors the actuator position and determines the target track for a seek operation.

•Controls the voice coil motor driver to align the actuator in a desired position.

•Constantly monitors error conditions of the servo and takes corresponding action if an error occurs.

•Monitors various timers such as head settle and servo failure.

•Performs self-checkout (diagnostics).

3.2Head disk assembly

The head disk assembly (HDA) is assembled in a clean room environment and contains the disks and actuator assembly. Air is constantly circulated and filtered when the drive is operational. Venting of the HDA is accomplished via a breather filter.

The spindle is driven directly by an in-hub, brushless, sensorless DC drive motor. Dynamic braking is used to quickly stop the spindle.

3.3Actuator

The read/write heads are mounted in the actuator. The actuator is a swing-arm assembly driven by a voice coil motor. A closed-loop positioning servo controls the movement of the actuator. An embedded servo pattern supplies feedback to the positioning servo to keep the read/write heads centered over the desired track.

The actuator assembly is balanced to allow vertical or horizontal mounting without adjustment.

When the drive is powered off, the actuator automatically moves the head to the actuator ramp outside of the disk where it parks.

4.4.1Drive format

Upon shipment from Hitachi Global Storage Technologies manufacturing the drive satisfies the sector continuity in the physical format by means of the defect flagging strategy described in Section 5.0 on page 14 in order to provide the maximum performance to users.

4.4.2Cylinder allocation

Physical cylinder is calculated from the starting data track of 0. It is not relevant to logical CHS. Depending on the capacity some of the inner zone cylinders are not allocated.

Data cylinder

This cylinder contains the user data which can be sent and retrieved via read/write commands and a spare area for reassigned data.

Spare cylinder

The spare cylinder is used by Hitachi Global Storage Technologies manufacturing and includes data sent from a defect location.

4.5Performance characteristics

Drive performance is characterized by the following parameters:

Command overhead

Mechanical positioning

-Seek time

-Latency Data transfer speed

Buffering operation (Look ahead/Write cache)

All the above parameters contribute to drive performance. There are other parameters that contribute to the performance of the actual system. This specification defines the characteristics of the drive, not the characteristics of the system throughput which depends on the system and the application.

4.5.1Command overhead

Command overhead is defined as the time required

from the time the command is written into the command register by a host

to the assertion of DRQ for the first data byte of a READ command when the requested data is not in the buffer

excluding Physical seek time and Latency The table below gives average command overhead.

	Command type (Drive is in quiescent state)	Time (Typical)	Time (Typical)
			for NCQ
		(ms)
			command (ms)*
	Read (Cache not hit) (from Command Write to Seek Start)	0.5	0.5
	Read (Cache hit) (from Command Write to DRQ)	0.1	0.2
	Write (from Command Write to DRQ)	0.015	0.2
	Seek (from Command Write to Seek Start)	0.5	not applicable

* SATA only

Table 4 Command overhead

4.5.2Mechanical positioning

4.5.2.1Average seek time (without command overhead, including settling)

Command Type	1D/2D
	Typical (ms)		Max (ms)
Read	14.0		14.7
Write	15.0		15.7

Table 5 Mechanical positioning performance

The terms “Typical” and “Max” are used throughout this specification with the following meanings:

Typical. The average of the drive population tested at nominal environmental and voltage conditions.

Max. The maximum value measured on any one drive over the full range of the environmental and voltage conditions. (See Section 6.4, “Environment” on page 41 and Section 6.5, “DC Power Requirements” on page 43.

Seek time is measured from the start of the motion of the actuator to the start of a reliable read or write operation. "Reliable read or write" implies that error correction/recovery is not used to correct arrival problems. The average seek time is measured as the weighted average of all possible seek combinations.

max.

Σ (max. + 1 – n) (Tnin + Tnout)

n=1

Weighted Average = __________________________________________________

(max. + 1) (Tnin + Tnout)

where: max = maximum seek length n = seek length (1 to max)

Tnin = inward measured seek time for an n-track seek Tnout = outward measured seek time for an n-track seek

4.5.2.2Full stroke seek (without command overhead, including settling)

Command Type	1D/2D
	Typical (ms)		Max (ms)
Read	27.0		30.0
Write	28.0		31.0

Table 6 Full stroke seek time

Full stroke seek is measured as the average of 1000 full stroke seeks with a random head switch from both directions (inward and outward).

4.5.2.3Single track seek time (without command overhead, including settling)

Common to all models and all seek modes

Function	Typical (ms)	Max (ms)
Read	0.8	1.5
Write	1.3	2.0

Table 7 Single Track Seek Time

Single track seek is measured as the average of one (1) single track seek from every track with a random head switch in both directions (inward and outward).

4.5.2.4Average latency

Rotational speed	Time for a revolution	Average latency
	(ms)	(ms)
7200 RPM	8.3	4.17

Table 8 Latency Time

4.5.3Drive ready time

Power on to ready		Typical (sec)	Maximum (sec)
1D model		8	20
2D model		10	20
Table 9 Drive ready time
Ready	The condition in which the drive is able to perform a media access command
	(such as read, write) immediately.
Power on	This includes the time required for the internal self diagnostics.

Note: Max Power On to ready time is the maximum time period that Device 0 waits for Device 1 to assert PDIAG–.

4.5.4Operating modes

4.5.4.1Operating mode descriptions

Operating mode	Description
Spin-up	Start up time period from spindle stop or power down
Seek	Seek operation mode
Write	Write operation mode
Read	Read operation mode
Unload Idle	Spindle rotation at 7200 RPM with heads unloaded
Idle	Spindle motor and servo system are working normally. Commands can be
	received and processed immediately

5.0Defect flagging strategy

Media defects are remapped to the next available sector during the Format Process in manufacturing. The mapping from LBA to the physical locations is calculated by an internally maintained table.

Shipped format

•Data areas are optimally used.

•No extra sector is wasted as a spare throughout user data areas.

•All pushes generated by defects are absorbed by the spare tracks of the inner zone.

N N+1 defect N+2 defect N+3

skip skip

Figure 1 PList physical format

Defects are skipped without any constraint, such as track or cylinder boundary. The calculation from LBA to physical is done automatically by internal table. Specification

2."I" designates an input to the drive.

3."I/O" designates an input/output common.

4."OC" designates open-collector or open-drain output.

5.The signal lines marked with (*) are redefined during the Ultra DMA protocol to provide special functions. These lines change from the conventional to special definitions at the moment the Host decides to allow a DMA burst if the Ultra DMA transfer mode was previously chosen via SetFeatures. The Drive becomes aware of this change upon assertion of the DMACKline. These lines revert back to their original definitions upon the deassertion of DMACKat the termination of the DMA burst.

DIOW-	Its rising edge holds data from the host data bus to a register or data register of the drive.
DIOR-	When low, this signal enables data from a register or data register of the drive onto data bus.
	The data on the bus shall be latched on the rising edge of DIOR-.
INTRQ	Interrupt is enabled only when the drive is selected and the host activates the nIEN bit in the
	Device Control Reg. Otherwise, this signal is in high impedance state regardless of the state
	of the IRQ bit. The interrupt is set when the IRQ bit is set by the drive CPU. IRQ is reset to
	zero by a host read of the status register or a write to the Command Reg. This signal is a
	3-State line with 24 mA sink capability.
DASP-	This is a time-multiplexed signal which indicates that a drive is active, or that device 1 is
	present. This signal is driven by Open-Drain driver and internally pulled up to 5 volts through
	a 10kΩ resistor.
	During Power-On initialization or after RESETis negated, DASPshall be asserted by
	Device 1 within 400 ms to indicate that device 1 is present. Device 0 shall allow up to 450
	ms for device 1 to assert DASP-. If device 1 is not present, device 0 may assert DASPto
	drive a LED indicator.
	DASPshall be negated following acceptance of the first valid command by device 1. At
	anytime after negation of DASP-, either drive may assert DASPto indicate that a drive is
	active.
PDIAG-	PDIAGshall be asserted by device 1 to indicate to device 0 that it has completed
	diagnostics. This line is pulled-up to 5 volts in the drive through a 10kΩ resistor.
	Following a Power On Reset, software reset, or RESET-, drive 1 shall negate PDIAGwithin
	1 ms (to indicate to device 0 that it is busy). Drive 1 shall then assert PDIAGwithin 30
	seconds to indicate that it is no longer busy and is able to provide status.
	Following the receipt of a valid Execute Drive Diagnostics command, device 1 shall negate
	PDIAGwithin 1 ms to indicate to device 0 that it is busy and has not yet passed its drive
	diagnostics. If device 1 is present, device 0 shall wait up to 6 seconds from the receipt of a
	valid Execute Drive Diagnostics command for drive 1 to assert PDIAG-. Device 1 should
	clear BSY before asserting PDIAG-, as PDIAGis used to indicate that device 1 has passed
	its diagnostics and is ready to post status.
	If device 1 did not assert DASPduring reset initialization, device 0 shall post its own status
	immediately after it completes diagnostics and clear the device 1 Status register to 00h.
	Device 0 may be unable to accept commands until it has finished its reset procedure and is
	ready (DRDY=1).
	Device 1 shall release PDIAG-/CBLID- no later than after the first command following a
	power on or hardware reset sequence so that the host may sample PDIAG-/CBLID- in order
	to detect the presence or absence of an 80-conductor cable assembly.

CSEL (Cable Select) (Optional)

The drive is configured as either Device 0 or 1 depending upon the value of CSEL.

•If CSEL is grounded, the device address is 0.

•If CSEL is open, the device address is 1.

KEY	Pin position 20 has no connection pin. It is recommended to close the respective position of
	the cable connector in order to avoid incorrect insertion by mistake.
IORDY	This signal is negated to extend the host transfer cycle when a drive is not ready to respond
	to a data transfer request and may be negated when the host transfer cycle is less than 240
	ns for PIO data transfer. This signal is an open-drain output with 24 mA sink capability and
	an external resistor is needed to pull up this line to 5 volts.
DMACK-	This signal shall be used by the host in response to DMARQ to either acknowledge that data
	has been accepted or that data is available.
	This signal is internally pulled up to 3.3 V through a 15 KΩ resistor. The tolerance of the
	resistor value is –50% to +100%.
DMARQ	This signal, used for DMA data transfers between host and drive, shall be asserted by the
	drive when it is ready to transfer data to or from the host. The direction of data transfer is
	controlled by DIORand DIOW-. This signal is used on a handshake manner with DMACK-.
	This signal is a 3-state line with 24mA sink capability and internally pulled down to GND
	through 10 KΩ resistor.

HDMARDY- (Ultra DMA)

This signal is used only for Ultra DMA data transfers between the host and the device.

HDMARDYis a flow control signal for Ultra DMA data in bursts. This signal is held asserted by the host to indicate to the device that the host is ready to receive Ultra DMA data in transfers. The host may negate HDMARDYto pause an Ultra DMA data in transfer.

HSTROBE (Ultra DMA)

This signal is used only for Ultra DMA data transfers between the host and the device.

HSTROBE is the data out strobe signal from the host for an Ultra DMA data out transfer. Both the rising and falling edge of HSTROBE latch the data from DD(15:0) into the device. The host may stop toggling HSTROBE to pause an Ultra DMA data out transfer.

STOP (Ultra DMA)

This signal is used only for Ultra DMA data transfers between the host and the device.

STOP shall be asserted by the host prior to initiation of an Ultra DMA burst. STOP shall be negated by the host before data is transferred in an Ultra DMA burst. Assertion of STOP by the host during or after data transfer in an Ultra DMA mode signals the termination of the burst.

DDMARDY- (Ultra DMA)

This signal is used only for Ultra DMA data transfers between the host and the device.

DDMARDYis a flow control signal for Ultra DMA data out bursts. This signal is held asserted by the device to indicate to the host that the device is ready to receive Ultra DMA data out transfers. The device may negate DDMARDYto pause an Ultra DMA data out transfer.

DSTROBE (Ultra DMA)

This signal is used only for Ultra DMA data transfers between the host and the device.

DSTROBE is the data in strobe signal from the device for an Ultra DMA data in transfer. Both the rising and falling edge of DSTROBE latch the data from DD(15:0) into the host. The device may stop toggling DSTROBE to pause an Ultra DMA data in transfer.

Device Termination

The termination resistors on the device side are implemented on the drive side as follows:

•33 Ω for DD0 thru DD15, DMARQ, INTRQ

•82 Ω for CS0-, CS1-, DA0, DA1, DA2, DIOR-, DIOW-, DMACK-

•22 Ω for IORDY
