PRODUCT DESCRIPTION

Major HDA Components

Drive Mechanism

A brush-less DC direct drive motor rotates the spindle at 5400 RPM (±0.1%). The dynamically balanced motor/spindle assembly ensures minimal mechanical run-out to the disks. A dynamic brake provides a fast stop to the spindle motor upon power removal. The speed tolerance includes motor performance and motor circuit tolerances.

Rotary Actuator

All Maxtor hard drives employ a rotary voice coil actuator which consists of a moving coil, an actuator arm assembly and stationary magnets. The actuator moves on a low-mass, low-friction center shaft. The low friction contributes to fast access times and low power consumption.

Read/Write Electronics

An integrated circuit mounted within the sealed head disk assembly (near the read/write heads) provides up to eight head selection (depending on the model), read pre-amplification and write drive circuitry.

Read/Write Heads and Media

Low mass, low force giant magneto-resistive read/write heads record data on 3.5-inch diameter disks. Maxtor uses a sputtered thin film medium on all disks for Maxtor hard drives.

Air Filtration System

All Maxtor hard drives are assembled in a Class 100 controlled environment. Over the life of the drive,

a 0.1 micron filter and breather filter located within the sealed head disk assembly (HDA) maintain a clean environment to the heads and disks. Maxtor drives are designed to operate in a typical office environment with minimum environmental control.

Microprocessor

The microprocessor controls the following functions for the drive electronics:

Command execution

Cache management

Data correction and error recovery

Diagnostic execution

Data sequencing

Head positioning (including error recovery)

Host interface

Index detection

Spin speed control

Seeks

Servo
