(3) Spindle motor

The disks are rotated by a direct drive Hall-less DC motor.

(4) Actuator

The actuator uses a revolving voice coil motor (VCM) structure which consumes low power and generates very little heat. The head assembly at the edge of the actuator arm is controlled and positioned by feedback of the servo information read by the read/write head. If the power is not on or if the spindle motor is stopped, the head assembly stays in the specific CSS zone on the disk and is fixed by a mechanical lock.

(5) Air circulation system

The disk enclosure (DE) is sealed to prevent dust and dirt from entering. The disk enclosure features a closed loop air circulation system that relies on the blower effect of the rotating disk. This system continuously circulates the air through the circulation filter to maintain the cleanliness of the air within the disk enclosure.

(6) Read/write circuit

The read/write circuit uses a LSI chip for the read/write preamplifier. It improves data reliability by preventing errors caused by external noise.

(7) Controller circuit

The controller circuit consists of an LSI chip to improve reliability. The high- speed microprocessor unit (MPU) achieves a high-performance AT controller.
