Product Description
Maxtor DiamondMax16 60/80/120/160GB 2-5
2.5 Major HDA Components
Drive Mechanism
A brushless 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. It also
provides 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
