3.0 Fixed-disk subsystem description
3.1 Control 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).
3.2 Head 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.
3.3 Actuator
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 position ing 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.

Notes:

Number of cylinders: For drives with capacities greater than 8.45 GB the Identify Device information word 01
limits the number of cylinders to 16, 383 per the ATA specification.
2.
Logical layout: Logical layout is an imaginary drive parameter (that is, the number of heads) which is used to access the drive from the system interface. The logical layout to Physical layout (that is, the actual Head and Sec­tors ) translation is done automatically in the drive. The default setting can be obtained by issuing an IDENTIFY DEVICE command.

4.5 Performance characteristics
Drive performance is characterized by the following parameters:
• Command overhead
• Mechanical head 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 tries to define the bare drive characteristics, not 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 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.

The terms “Typical” and “Max” are used throughout this document and are defined as follows:
Typical The average of the drive population tested at nominal environmental and voltage conditions. Max Maximum value measured on any one drive over the full range of the environmental and voltage
conditions. The seek time is measured from the start of the actuator’s motion to the start of a reli­able read or write operation. A reliable read or write implies that error correction or 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 (m10 n)(Tnin + Tnout)
n=1
Weighted Average = ––––––––––––––––––––––––––––
(max + 1)(max)
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
4.5.2.2 Full stroke seek time (without command overhead, including settling)

Read Write
15.1 18.1
16.1 19.1 Read (Quiet Seek mode) 32.5 35.5 Write (Quiet Seek mode) 33.5 36.5
Full stroke seek is measured as the average of 1,000 full stroke seeks with a random head switch from both direc­tions (inward and outward).
4.5.2.3 Single track seek time (without command overhead, including settling)
Table 7: Single track seek time
Function Typical (ms) Max (ms)
Read 0.8 1.5
Write 1.3 2.0
Read (Quiet Seek mode) 0.8 1.5
Write (Quiet Seek mode) 1.3 2.0
Single track seek is measured as the average of one (1) single track seek from every track in both directions (inward and outward).
