FIXED HARD DISC DRIVE ASSEMBLY AND CLEAN AIR SYSTEM

摘要

Disclosed is a fixed hard disc drive, including a hermetically sealed housing with an air cleaning means, for use in connection with microcomputers and other data handling equipment. The drive assembly includes a cylindrical portion and a rectangular portion. A plurality of discs are supported on a drive shaft for rotation in the cylindrical portion and an external disc drive mechanism drives the shaft. A filter is disposed at one end of the rectangular portion and has an input side disposed to receive air which is pumped by the rotating discs and provides clean air to the center of the disc and spindle whereby the air can travel outwardly over the disc to cleanse it. A plurality of magnetic heads are supported in cooperative relationship with the disc surfaces and a head support and drive assembly at the other end of the rectangular housing moves the heads into cooperative relationship with the discs. An external motive mechanism drives the heads to various radial locations on the disc surfaces. The disc drive is plug compatible with conventional floppy disc drives but the hard discs have higher storage capacity.
