摘要： A miniaturized optical disc memory is receivable in a slot, of about 17 mm height, normally accommodating a floppy disc drive. A base includes a base plate with integral, peripheral sidewalls and an internal lateral partition wall which define a cartridge receiving slot on the upper surface of the base plate. First and second support plates extend from the partition wall to the rear peripheral sidewall of the base and define respective, first and second upper mounting surfaces and lower first and second cavities respectively receiving an ejection motor and a fixed optical system, individual optical components being mounted and aligned on integral, precision machined blocks in the second cavity for transmitting a laser beam and receiving a reflected beam along a central, longitudinal optical axis beneath the base plate. A first base plate aperture accommodates a lens carriage driven in reciprocating motion along the axis for receiving and redirecting the laser beam vertically for scanning an optical disc and receiving a reflected beam and redirecting same to the fixed optical system. The movable optical system is locked in a rest position and is released by insertion of a cartridge to permit scanning movement thereof. A disc drive unit is mounted beneath the base plate for reciprocating vertical movement through a second aperture therein to a raised position for engaging and driving, in rotation, an optical disc of a cartridge inserted into the apparatus and to a lowered position for releasing the cartridge and permitting ejection thereof.
