Abstract

A technique is described whereby a 3-1/2-inch diameter magnetic disk drive mechanism may be installed in a position provided for a 5-1/4- inch diameter magnetic disk drive mechanism, through the use of an interface assembly and a circuit adapter card. The interface assembly consists of a tray assembly, with a pair of rails, designed to be slid into the space provided for the larger drive. Also, a circuit adapter card provides the interconnection of both signal and power connections as required for the smaller drive. This enables the same input cable assembly to be used for both types of drives.

Interface Assembly for Interchangeable Electromagnetic Devices

A technique is described whereby a 3-1/2-inch diameter magnetic disk drive mechanism may be installed in a position provided for a 5-1/4- inch diameter magnetic disk drive mechanism, through the use of an interface assembly and a circuit adapter card. The interface assembly consists of a tray assembly, with a pair of rails, designed to be slid into the space provided for the larger drive. Also, a circuit adapter card provides the interconnection of both signal and power connections as required for the smaller drive. This enables the same input cable assembly to be used for both types of drives. Tray assembly 10, as shown in the drawing, allows 3-1/2-inch diameter magnetic disk drive mechanism 11 to be fastened to tray assembly 10 by means of screws 12, passing through access holes 13, which are located on the side plate of tray assembly 10, then screwed into threaded holes 14, located on flexible tabs 15. Flexible tabs 15 are so designed as to compensate for variations in dimensions of drive 11 and tray 10. Bezel 16 is then snapped into position at the front of the assembly by means of flexible locking tabs 17 into slots 18 of drive 11. Bezel 16 incorporates slot 19 so that a magnetic disk may be inserted during operation of the system. Hole 20 lines up with eject button 21, and hole 22 lines up with indicator light 23. Rails 24 are then fastened to tray 10, by means of screws 25, through recessed holes 26 into threaded holes 27. When assembled, the dimensional distance of mounted rail...
