PRODUCT DESCRIPTION Major HDA Components Drive Mechanism A brush-less DC direct drive motor rotates the spindle at 7200 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. All Maxtor hard 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 S.M.A.R.T. 2 - 4
