ABSTRACT:
A self-timing optic lathe, comprising a turntable for rotating an object disc, an offset code track carried by the turntable and embodying an encoded control signal, a read laser for optically reading the encoded control signal from the code track, a write laser for optically recording an information signal on the object disc, an optical carriage for moving the write laser and the read laser in a radial direction across the turntable relative to the code track, and a timing and control circuit connected to the write laser and the read laser for reading the control signal and in response controlling rotation of the turntable and operation of the write laser to record the information signal independently of the speed of rotation of the turntable.
