    摘要: An optical recording member comprising a recording layer containing a light abosrbing substance supported on a substrate in which recording is made by the thermal deformation of the recording layer owing to laser beams and reproduction is made by the reading the difference of the reflection between the non-deformation portion and the deformation portion, said light absorbing substance being represented by the following formula: ##STR1## wherein one of X and Y is --O(C.sub.2 H.sub.4 O).sub.n R wherein R is an alkyl group which may be branched and n is a number of from 1 to 6, and the other is a hydrogen atom, and A is VO, Cu, Ni, or Co.

    摘要: By use of a substrate which can be stably formed and has a relatively small groove depth, a very high density optical recording medium having good recording/reading characteristics is provided. In an optical recording medium of a surface incidence type, in which a reflective layer, a recording layer containing a dye as a main component and a cover layer are sequentially formed on a substrate having guide grooves formed therein, a guide groove part on a far side from a plane of incidence of a recording/reading light beam on the cover layer is set as a recording groove part, and reflected light intensity in a recorded pit portion formed in the recording groove part is increased by a phase shift and is set higher than reflected light intensity in unrecorded.
