Abstract: PROBLEM TO BE SOLVED: To enable the reproduction up to the shortest domain length to assure high density reproduction and a long operation life of a semiconductor laser by converting a laser beam into a pulse in the magneto-optical reproducing apparatus. SOLUTION: In the case of recording, a signal modulated by a modulation circuit 32 is converted to a pulse of the predetermined duty with a timing pulse generating circuit 33 to drive a magnetic head 37 and an optical head 36. In this case, radiation of laser beam is not conducted to the transition area of the pulse inversion. In the case of reproducing, a signal is amplified and integrated by a low-pass filter 41 and is then decoded by a decoder 43 in synchronization with the clock generated by a clock generation circuit 42. In this case, the servo circuit 39 controls a motor 38 and an objective lens of the optical head with the error signal from the optical head 36 and the clock signal to control the tracking and focus.  Meanwhile, a synchronous signal generating circuit 44 converts the synchronous signal. to a pulse depending on the clock and sends this pulse to a drive circuit 35 to control t he optical head 36. Thereby, reproduction can be made up to the shortest domain length of 0.3μm or less.
