Abstract
A disk drive assembly which is resistant to physical shocks and thermally caused distortion, including an end plate, a casing attached to the end plate, and a base plate enclosed in the casing and mounted to the end plate. The end plate supports a rotatable disk and an actuator assembly for reading information from and recording information on the disk. The end plate and the casing form a seal to provide a controlled environment within the casing and the base plate is attached to the end plate in the controlled environment.
Claims5
A disk drive, comprising:
- a shock frame having mounting points;
- control means for generating control signals;
- and
- a hard disk drive assembly, mounted on said shock frame at said mounting points, comprising:
- an end plate having a peripheral edge,
- a gasket provided on said peripheral edge of said end plate,
- a casing having an opening, said casing being attached to said end plate so that said opening of said casing engages said gasket to provide a sealed environment within said casing,
- a planar base plate having a first end mounted to said end plate so that said base plate is substantially perpendicular to said end plate and a second end mounted to said casing, said base plate residing in said sealed environment,
- a top plate mounted on said base plate,
- means, rotatably supported by said base plate, for storing information,
- rotating means, responsive to said control signals, for rotating said disk means,
- read and record means, responsive to said control signals, for reading information from said means for storing and recording information on said means for storing,
- means for transferring said control signals from the control means to the environment within said casing, and
- flexible circuit means for electrically interconnecting said means for transferring with said read and record means and said rotating means.

A hard disk drive assembly, comprising:
- an end plate;
- a casing attached to said end plate;
- a gasket provided between said casing and said end plate to form a seal and to provide a sealed environment isolated from ambient conditions within said casing;
- a planar base plate, said base plate having a first end semirigidly mounted to said end plate and a second end attached to said casing, said base plate residing in the sealed environment;
- a planar top plate mounted on said base plate;
- a disk assembly mounted on said base plate, said disk assembly including a disk and means for rotating said disk;
- and
- read and record means supported by said top and base plates for reading information from said disk and recording information on said disk.
