Abstract: PROBLEM TO BE SOLVED: To provide an anamorphic prism having a less degree of frequency dependency. SOLUTION: Two prisms 1 and 2 are formed out of different glass materials, and the magnifications thereof are also optimized at values different from each other. As a result, what is called achromatic type anamorphic prism having the characteristic that an outgoing beam direction is constant regardless of a wavelength fluctuation can be obtained. When the anamorphic prism so formed is used for the optical system of an optical disc system, the positional fluctuation of a beam spot due to the fluctuation of laser wavelength can be prevented.

Abstract: PROBLEM TO BE SOLVED: To further increase the recording density of a magneto-optical recording medium by eliminating a ghost phenomenon in a domain wall displacement detection(DWDD) system. SOLUTION: During a reproducing of the signals from a magneto-optical recording medium by a DWDD system, a mark position recording system is selected for the recording against the medium. Unlike a mark edge recording system, in which signals are recorded by modulating recording mark lengths, the lengths of the recording marks are always made constant in the mark position recording system and the recording mark length is made very short. The ghost phenomenon in the DWDD system is not generated if the recording mark is sufficiently small. Thus, by selecting the mark position recording system for the recording, the problem of the ghost phenomenon in the DWDD system is resolved.
