Abstract
A compact disk drive useful with a laptop computer comprises at least one glass disk, thin film read/write heads and a head actuator preferably made of magnesium material. The drive motor hub and hub flange are made of steel and the magnet housing for the actuator is made from an integral steel unit. A flexible cable assembly, which is connected to the read/write head circuits and to external circuitry for data processing and for providing control signals, is formed with two flexible sections. Each section is attached to the head actuator and to stationary posts of the disk drive housing thereby balancing the forces applied to the actuator when it is moved for head accessing. A clamp for holding the disk to the motor hub is designed to minimize distortion and to prevent shifting and misalignment of the disk relative to the center of the motor hub.
