Desiccant housing within a high performance standard configuration disc drive having smaller than standard disc

摘要

A magnetic disc drive assembly comprises a disc drive housing having an external three-dimensional configuration matching a standard configuration. A disc drive (100) is supported in the housing (102) and includes a stack of rotatable rigid magnetic recording discs (104) in a unique configuration wherein each disc has a diameter smaller than the diameter or rigid discs ordinarily contained in a disc drive housing having the standard configuration. Optionally, the stack of discs includes a number of discs greater than that normally housed in a disc drive housing having the standard configuration. Various techniques are employed to achieve the unique disc configuration, including a stop mechanism (151, 152, 153, 154) attached to the yoke of an E-block assembly (142), a conductor assembly (214) electrically connecting transducers (144) on the E-block to a flex circuit (172, 220) and employing fins (218) supported in slots (204) in the E-block, a cable connector (130) mounted to a circuit board (131) supported on the disc drive housing and having a connector housing (300) having a surface (312) conforming to a curved edge portion (111) of the disc drive housing, and a desiccant housing (186) providing structural support for the disc drive housing. The top opening of the dessicant housing (186) may form a plane (196) which slopes in relation to the bottom wall of the drive chamber and may be provided with a bottom opening for insertion of the desiccant.
