Cartridge positioning and interlock apparatus

In a disk drive housing, having a plurality of rectangular-shaped disk drive cartridge mounting openings for housing an associated disk drive cartridge, each of said openings having a front, a back wall, a top wall and two side walls which define said opening, a disk drive interlock apparatus for mechanically securing a disk drive cartridge, having a front side and a back side, into one of said disk drive cartridge mounting openings, comprising:

• a pair of tapered channel means, each located on said top wall of said opening, extending from said front to said back wall and mating with a corresponding rail on said disk drive cartridge and including a polygonal channel that piecewise approximates a semicircular shaped channel, for guiding the insertion of said disk drive cartridge into said opening, wherein the taper of said tapered channel means provides a guide opening having diminishing width from said front to said back wall of said opening;
• elastomeric stop means located on said back wall of said opening for elastically resisting the complete insertion of said corresponding disk drive cartridge into said opening;
• camming means for compressing said elastomeric stop means to lock said corresponding disk drive cartridge into said opening, including:
• pin means rotatably mounted on said disk drive cartridge for engagably interconnecting with a slot on said top wall of said opening to force said disk drive cartridge into said opening;
• lever means rotatably mounted on said disk drive cartridge and connected to said pin means for rotating said pin means into said slot.
