Abstract: PURPOSE:To obviate the generation of corrosion in a recording layer even when the recording medium is exposed to a high-temp. and high-humidity atmosphere by providing a UV curing type resin material contg. a photopolymer, initiator on the recording layer, then subjecting the layer to irradiation with UV rays and irradiation with electron beams. CONSTITUTION:After the recording layer 2 is formed on, for example, a polycarbonate substrate 1, a protective layer 3 is formed thereon. The layer is irradiated with about 300 to 1,500mJ/cm UV rays and is then irradiated with about 0.5 to 3Mrad electron beams, by which the optical recording medium is obtd. The recording layer is irradiated with a proper quantity of the electron beams after the curing of the film is sufficiently executed by the UV rays in such a manner, by which the quantity of the residual double bonds of the overcoat layer on the recording layer side is further decreased and the steam barrier property of the film is improved. The corrosion of the recording layer is thus prevented and the durability is improved.

Abstract: PURPOSE:To ensure that the generation of scratch is minimized and the settlement of dust is prevented from occurring by providing an organic protective film on the incident surface side of a photorecording medium using a laser beam and forming the organic protective film with a mixture of an acrylic material and a reaction activator having an electric charge preventing function using radiation-curing technique. CONSTITUTION:A photorecording medium consists of, for example, a substrate where a recording pit or a guide groove 1 is formed, a reflective film or a recording film 3 and an organic protective film 5. A laser beam is allowed to enter from the top of the substrate 2, then a reflected light from the reflective film of the substrate 2, then a reflected light from the reflective film or recording film 3 is received and this received light is converted to information by a light/electricity conversion element. The organic protective film 5 is formed by curing a mixture of an acrylic material and a reactive activator with an electric charge prevention function using radiation. The reactive activator with an electric charge prevention function is cured at the same time as when the acrylic material is cured by radiation. Further, part of the three-dimensional mesh structure of an acrylic protective film is carried by the reactive activator and these two become firmly bound together. In addition, the activator has an electric charge prevention function as it is prevented with an activation function. A surfactant of anionic, cationic, nonionic or dipolar type is used as the reaction activator.

CONSTITUTION:Slide contact parts 2 are provided to face to a magnetic head 3 with a disk 1 between and equipped with a recessed part 12, which is extended to face to this magnetic head 3 in the moving range of the magnetic head 3, first regulating face 13 on the upstream side of a rotating direction and second regulating face 14 on a downstream side. The width of the second regulating face in the rotating direction is made less than 3mm and both end parts on the cross section of the second regulating face 14 are formed so that a curvature radius can be less than 1mm. Further, the coarseness of the surfaces for the regulating parts of the first and second regulating face 13 and 14 is made less than 0.5mum in the average coarseness of a central line. Accordingly, projections are removed in the change corner parts of end parts on the both regulating faces 13 and 14 and the surfaces are made smooth. Thus, damage to the disk is prevented and durability is improved.
