    摘要： A magneto-optical disc includes a substrate, a recording layer, and a protective coating comprised of a resin and a lubricant. The disc is operated for magneto-optical recording in a magnetic field modulation mode such that the protective coating is in sliding contact with a magnetic head. The lubricant is a higher fatty acid ester R.sup.1 --COO--R.sup.2 wherein R.sup.1 is a saturated or unsaturated aliphatic C.sub.10 -C.sub.30 hydrocarbon residue, and R.sup.2 is a saturated or unsaturated aliphatic C.sub.10 -C.sub.30 hydrocarbon residue. Alternatively, the protective coating is formed by curing with radiation a composition containing a lubricant and a radiation-curable compound such that micropores are locally formed in or near the outer surface of the protective coating, the lubricant being distributed in the micropores. In either case, the protective coating is effective for minimizing friction with the magnetic head.

    摘要： A magneto-optical disc includes a recording layer (4) and a protective film (7) of radiation-cured resin on a substrate (2). Information is written in the recording layer with the aid of a magnetic head in sliding contact with the disc. In a first form, when the protective film is subject to a micro-vibration scratch test by setting the disc in a thin film scratch tester equipped with a diamond indentor having a radius of curvature R of up to 50 .mu.m, the relationship: 0.8.ltoreq.L/R.sup.2 .ltoreq.2.7 is met wherein L is the critical load (N.m) under which the thin film is scratched. In a second form, the protective film has a dynamic modulus of 5.0.times.10.sup.9 to 4.0.times.10.sup.10 dyn/cm.sup.2 at 100.degree. C. The disc is highly durable.

    摘要： The invention provides an optical disc comprising a circular glass substrate (2) having information-carrying means (3) on one major surface. A protective member (4) of a resin includes a circular flat portion (42) and an annular rim (41) extending perpendicular from the periphery of the flat portion (42). The glass substrate (2) is integrally joined to the protective member (4) such that the information-carrying means (3) of the glass substrate (2) may face the covering portion (42) of the protective member (4). The outer side of the glass substrate (2) is surrounded by the protective member rim (41) to leave a shock absorbing space therebetween. The invention prevents the glass substrate from failure at its corner when impact is applied to the disc.

    摘要： An optical information recording medium (1) includes on a substrate (50), a ROM layer (20), a RE layer (40), an intermediate layer (30) separating the ROM layer (20) and the RE layer (40), and a light transmitting layer (10) provided farthest from the substrate (50). The RE layer (40) is an information recording layer provided most farthest from the light transmitting layer (10), and is a recording layer of BCA recorded in a format easily determinable as compared to an information recording format used in the ROM layer (20), and antifouling property of a surface of the light transmitting layer (10) is set based on the RE layer (40). This makes it easy for the recording and reproducing apparatus to confirm a disc type, allows for sharing one recording and reproducing apparatus with other types of optical discs, and simplifies the disc production. Furthermore, an optical information recording medium is accomplished, in which outdated data on the ROM layer is replaced by recording, on the RE layer, updated data obtained while Internet connection can be established.
