Inventor: MASUDA TOSHIYUKI
IPC: G11B7/2531
Filed: 1988-11-17
Abstract: PURPOSE:To improve sensitivity at the time of recording by irradiating the group of a pre-group with laser light from a substrate side while rotating an information recording medium so that information may be recorded. CONSTITUTION:A hole part 17 is provided in the center of the disklike resin substrate 11 of the information recording medium 10 and the non-recording areas 18 and 19 of an inner circumferential side and an outer circumferential side are respectively set on the periphery of the hole part 17. A recording layer 20 is formed between both non-recording areas 18 and 19 and a space part 22 is formed by the resin substrate 11 and a resin film 12 having projecting and recessed parts. While rotating the recording medium 10, the group of the recording layer 20 is irradiated with the laser light so that the information may be recorded. Therefore, in the case of irradiating the group of the recording medium 10 which is protected by the resin film 12 having the projecting and recessed parts with the laser light, the contact area of the resin film 12 with the recording layer 20 is made small. Thus, the loss of energy caused by conduction of heat is reduced and the sensitivity at the time of recording is improved.
