Title: Production of optical recording medium
Inventor: YASHIRO TORU
IPC: G11B7/246
Filed: 1991-11-20
Abstract: PURPOSE:To enable the production of the write-once/read-many-times (WORM) optical recording medium having a ROM region without selective coating and to improve the recording signal characteristics in both of the ROM region and a recordable region. CONSTITUTION:A substrate which is set with the width of guide grooves narrower than the pit width of information pits or a substrate which is set with the depth of the guide grooves shallower than the depth of the information pits is used as a substrate. A light absorptive layer essentially consisting of a dyestuff is provided by spin coating directly or via another layer on this substrate. A protective layer is then provided directly or via another layer thereon, by which the optical recording medium is constituted. As a result, the production of the WORM optical recording medium having the ROM region is enabled without selective coating and the quantity to fill the information pits and guide grooves with the dyestuff is controlled. The recording signal characteristics in both regions are thus improved.
