Disk housing for disk drive mass storage unit

摘要

A housing (1-10) for a disk (1-12) used in a "Winchester"-type disk mass information storage unit in a data processing system. The housing is symmetrical about the plane of the disk, and supports the disk spindle (2-33) on both sides of the disk. The housing includes two substantially identical members (1-16, 17) fitted together in a clamshell-type arrangement. The housing includes a housing extension (1-26) for receiving and supporting the read/write heads (1-14) and actuator (1-15) therefor from both ends thereof. The members forming the housing are preferably thin walled castings, and may include fins (1-104) to dissipate heat or to enhance the housing's mechanical rigidity.
