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.

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.
