ABSTRACT:
A two and one-half inch form factor disk drive. The disk drive includes a base having a top and a bottom, and at least one storage disk. A spin motor is secured to the base and the disk is mounted thereon. Read/write heads are provided for reading information from and writing information on the storage disk. The read/write heads are supported and positioned by an actuator in response to control signals, the actuator having top and bottom plates comprising a support structure, the top plate being supported on the base. A cover is sealably attached to the base, such that the base and cover enclose the disk, the heads, and the actuator. In addition, control electronics, mounted on the head-disk assembly so that the control electronics are adjacent to the bottom of the base, generate the control signals to control the actuator means and provide information signals to and receive information signals from the read/write heads. The disk drive has an overall maximum height equal to or less than substantially twelve and one-half millimeters (12.5 mm). In a further aspect, the disk drive further includes a header assembly for electrically coupling a printed circuit board including the control electronics to the actuator, read/write heads and spin motor. The drive further includes an actuator assembly fabricated such that the actuator assembly and the header assembly are secured to a single mounting member thereby providing an integrated header and actuator assembly for insertion into the disk drive.
