摘要： An optical information recording medium which makes it possible to reduce the noise level and improve the C/N ratio and store record data for a long time period. An optical information recording medium has a recording layer formed on a substrate, for having a laser beam irradiated thereto for recording and reproduction of record data. The recording layer includes a first sub-recording film and a second sub-recording film. The first sub-recording film is formed of a first material containing Si as a main component. The second sub-recording film is formed of a second material containing Al as a main component and having Mg added thereto, and disposed in the vicinity of the first recording film. The laser beam is irradiated to the recording layer via a light transmitting layer formed in a manner covering the recording layer.

摘要： An optical information medium includes a disk-shaped substrate (100) having a center hole (101), an annular information recording area thereon, and an annular resin-based light-transmitting layer (102) thereon by which recording/reading laser beam is transmitted to the information recording area. The light-transmitting layer (102) terminates at a radially inner periphery which forms an annular raised rim (6). The rim is effective for protecting the light-transmitting layer from damages and dust adhesion, and when a plurality of such media are stacked, preventing the media from intimate contact.

摘要： A magneto-optical recording disc adapted for magneto-optical recording in the magnetic field modulation system by means of a magnetic head in continuous contact with the disc includes a recording layer on a substrate and a wear resistant resinous coating thereon. The coating is formed of a resin containing carbon particles having a mean particle size of 1 to 15 .mu.m. The magnetic head is in sliding contact with the surface of the coating during operation. The coating is effective for reducing friction with the magnetic head and retains such reduced friction over a long time.
