Abstract
A two and one half inch form factor single disk drive has a height of 0.60. The spin motor is mounted in a recess in a housing base to reduce height of the housing. A printed circuit board is mounted to the base with all components of the circuit board being mounted on one side of the board opposite from the base. The cover and base are preferably made of cast aluminum alloy with the cover being convex configured for added strength.
Claims13
A disk drive having a length, a width, and a height, comprising
- a base,
- a cover configured to mate with said base and define a chamber having a controlled environment, said cover having a length and a width, and a convex cross section over the width of the cover extending outwardly from said base thereby enhancing the strength of said cover and said controlled environment to atmospheric pressure changes,
- said base and cover conforming to a form factor in which the length of the drive is approximately the width of a three and one-half inch drive, the width is approximately one-half of the length of a three and one-half inch drive, and the height is approximately 0.60 inch,
- a single-disk magnetic storage medium rotatably positioned in said chamber,
- a spin motor mounted to said base and having a spindle for rotatably supporting said single disk storage medium,
- actuator means including a rotary voice coil motor mounted to said base, a plurality of suspensions extending from and driven by said rotary voice coil motor, and a plurality of pick-up heads with each head mounted to an end portion of an extension for movement across a surface of the storage medium for recording and accessing data magnetically stored on the surface,
- latch means for securing said suspensions and heads over a non-data region of the storage medium, and
- circuit means for controlling said actuator means in recording and accessing data.
