3 Fixed 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.

4.4Drive organization

4.4.1 Drive 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 on page 23 in order to provide the maximum performance to users.

4.4.2 Cylinder 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.

4.5.1 Command overhead

Command overhead is defined as the time required

from the time H->D Reg FIS w/ command bit is sent by host

to the time

PIO Set Up FIS is sent by device(PIO Read/Write)

DATA FIS is sent by device(DMA Read)

DMA Activate FIS is sent by device(DMA Write)

DMA Set Up FIS is sent by device(NCQ Read/Write)

Seek Start (Read cache not hit or Seek)

The table below gives average command overhead.

Command type (Drive is in quiescent state)	Typical time (ms)	Typical time for NCQ
		command (ms)
Read (Cache not hit)	0.5	0.5
Read (Cache hit)	0.1	0.2
Write	0.015	0.2
Seek	0.5	not applicable

Table 8 Command overhead

4.5.2 Mechanical positioning

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

Command Type	1 Disk model		2 Disk model
	Typical (ms)	Max (ms)	Typical (ms)	Max (ms)
Read	14.0	14.7	8.5	9.2
Write	15.0	15.7	9.5	10.2
Read (Quiet Seek mode)	14.0	14.7	14.0	14.7
Write (Quiet Seek mode)	15.0	15.7	15.0	15.7

Table 9 Mechanical positioning performance

The terms “Typical” and “Max” are used throughout this s

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 6.2, “Environment”28 and Section6.3page,“DC Powerments”Requireon page 30.)

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.

(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

- Hitachi hard disk drive specifications –

4.5.2.2Single 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 10 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).

4.5.2.3Average latency

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

Table 11 Latency Time

4.5.3Drive ready time

Power on to ready	Typical (sec)	Maximum (sec)
1D model	8	20
2D model	10	20

Table 12 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.

4.5.4 Operating 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
Standby	Actuator is unloaded and spindle motor is stopped.	Commands can be received
	immediately
Sleep	Actuator is unloaded and spindle motor is stopped.	Only soft reset or COMRESET can
	change the mode to standby

Note: Upon power down or spindle stop a head locking mechanism will secure the heads in the OD parking position.

4.5.4.2Mode transition times

Mode transition times are shown below.

	From	To	RPM	Typical Transition		Max Transition
					time(sec)	time(sec)
	Standby	Idle	0 -> 7200	8 (1Disk model)		20
				10	(2Disk model))
	Idle	Standby	7200 -> 0		Immediately	20
	Standby	Sleep	0		Immediately	Immediately
	Sleep	Standby	0		Immediately	Immediately
	Unload idle	Idle	7,200		0.7	1
	Idle	Unload Idle	7,200		0.7	1
	Low RPM Idle	Idle	4500 -> 7200	3	(1 Disk model)	10
				4	(2 Disk model)

Note: The command is processed immediately but there will be an actual spin down time reflecting the seconds passed until the spindle motor stops.

Note: Low rpm idle mode is supported on specific drive PN, only.

5 Defect 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

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.
