Abstract

A record drive and positioning assembly particularly adapted for disc records used for recording of digital information and for use in association with computers. The unit embodies a record driving spindle or hub and clutch. The record is insertable into the unit through a hinged door. Ejector mechanism is provided in association with a latch, the ejector being operative to eject the record unless it is inserted fully in a latching position. The mechanism provides for "feel" so that the operator will know when the record is fully inserted. During closing of the door, a pin will unlatch the ejector allowing the ejector to move the record sufficiently to cause it to accurately register with the driving hub and clutch. When the door is opened by being lifted, the ejector will eject the record from the unit.
