Abstract: On a surface of a transparent substrate 1 having a preformat pattern 2 formed thereon are laminated a first recording layer 4 in which a recording state exists in one different magnetic field region of an applied external magnetic field and a second recording layer 6 in which two recording states exist in magnetic field regions different from that for the first recording layer. As required, dielectric layers 3, 5 and 7, a reflecting layer 8 and a protection layer 9 can be laminated. The 4-valued recording of information becomes possible by assigning information signals “1”, “0”, “3”, and “2” to H0, H1, H2 and H3, respectively.

Abstract: An optomagnetic recording and reproducing system has been developed which demonstrates superior performance when used with multilayer recording substrates. The system features an optical head and magnetic head disposed opposite to each other on different sides of the recording substrate. The novel magnetic head can either incorporate a number of independently driven subheads, or alternately it can be constructed by placing multiple independently driven windings on a single head. Biasing of the magnetic head can either be performed externally using an external magnet or by providing a bias with one of the windings or sub-heads. The resulting optomagnetic recording and reproducing system is suitable for multi-valued recording of an optomagnetic recording medium.

Abstract: An optical information recording/reproducing apparatus includes signal recording means for recording a signal on a film. The signal is recorded by raising the temperature of the film with a writing laser beam. A signal reproduction apparatus reproduces the signal by irradiating the film with a reading laser beam. There is an optical system provided in common to both the writing laser beam and the reading laser beam. The signal recorded on the film is reproduced substantially simultaneously with the recording of the signal in order to allow for confirmation of the signal that has been recorded. A modulating circuit is provided for modulating the intensity of the writing laser beam with a frequency of at least twice as high as the maximum frequency of the signal to be recorded.
