Disc recording apparatus including integral track zero and crash stop

A positioning assembly for magnetic heads in a disc apparatus including a band drive. The drive includes a relatively temperature insensitive band drive pulley which is employed to preload the positioning apparatus to minimize backlash runout and the like.

Head positioning assembly for disc apparatus

A disc drive assembly including a main housing containing a plurality of stacked discs supported on a rotating spindle is disclosed herein. This assembly also includes an air filter arrangement which defines a path of circulating air confined to a generally planar area within the housing. The support spindle includes a slot and an array of holes for directing the circulating air towards the discs in order to provide thermal balance.

Fixed hard disc drive assembly and clean air system

Disc drive assembly

A hard fixed head disc drive assembly having a rotating record disc with a transducer cooperating with the surface of the disc. The transducer is mounted on a carriage which has three spaced, grooved bearings, two of which are received by a fixed cylindrical track, the third bearing engages a spring-loaded cylindrical track which urges said first two bearings against said fixed track, whereby the carriage is centered on said tracks for movement therealong radially of said disc surface.
