Abstract: An optical data recording system has real time error checking by sensing the level of reflected radiation from the high energy level pulse used to form a spot on a disc, and then comparing the sensed level with a reference signal to thus sense a recording failure or defect in the disc. The sensed signal may be voltage shifted by passing through a coupling capacitance with the output discharged during an initial portion of the recording. Additionally, the reference signal may be derived from the sensed signal by passing through a second capacitive coupling circuit whose output is clamped to zero during a standby mode, the reference output being inverted and reduced by a fixed ratio to provide a proper reference voltage.

Abstract: A recording light beam from an argon laser is modulated with an electrical recording signal and then recorded on a rotating disc-shaped record medium. Immediately after this recording, a recorded signal on the record medium is reproduced with a light beam from a helium-argon laser and converted into an electrical signal. Duty cycles of both signals are sensed by respective duty cycle sensors. A differential amplifier produces a differential signal between the sensed duty cycles and supplies it to an optical modulator arranged to control the output of the recording laser. The modulator controls the recording light beam to its optimum light level for recording in response to the differential signal which was detected just before its modulation.
