초록 ▼

The present invention provides a disk drive apparatus for use in computer systems and especially in computer systems where size and weight are of paramount concern, such as lap top computer systems. The preferred embodiment of the disk drive apparatus includes a 2½″magnetic disk that preferably provides 20 to 40 megabytes of storage within a foot print area of approximately 2.8 inches by approximately 4.0 inches. Further, the disk drive apparatus possesses a height dimension of 0.630 inches or less. This height dimension is achieved, in part, by providing a low profile spin motor to rotate the magnetic disk. The low profile spin motor uses high energy magnets that are preferably made of a material that includes a rare earth, such as neodymium or samarium. The disk drive apparatus also employs a rotary actuator having a voice coil assembly of reduced height that is achieved by using the housing as a flux return path for magnet fields produced by the voice coil assembly. The present invention also provides an improved ambient filter that reduces the penetration of ambient water vapor into the housing of the disk drive apparatus. An improved desiccant located, at least in part, within the housing is also provided by the present invention. Additionally, the invention provides a flex circuit having a geometry that results in substantially zero torque applied to the rotary actuator. Also provided is a distributed frame apparatus that, besides connecting the housing to a printed circuit board, also provides side, top and/or bottom mounting capability and shock absorbing capability. The distributed frame also avoids the need for grounding.
