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 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.

Notes:
1Number of cylinders: For drives with capacities greater an 8.45 GB the IDENTIFY DEVICE information word 01
limits the number of cylinders to 16,383 per the ATA specification.
2Logical 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

4.4.1 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 5.0 on page 19 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.

4.5 Performance 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 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.

Table 8 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 6.2, “Environment” on page 24 and Section 6.3, “DC Power Requirements” on
page 26.)
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)

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
