ABSTRACT:
An optical recording medium and a recording method therefor in which a recording layer group and a light-absorbing and heat-generating layer for absorbing radiated light to convert the absorbed light into heat are formed on a substrate. The recording layer group is formed of thermo-sensitive recording layers capable of recording thereon information in the form of a light signal stacked alternatingly with heat insulating layers. Laser light emitted from a luminous source in a recording apparatus is condensed through an objective lens so as to be focused on the light-absorbing and heat-generating layer, so that when heat of a predetermined quantity or more is generated by the light-absorbing and heat-generating layer, the heat reaches the recording layers successively stepwise due to the heat insulating functions of the respective heat insulating layers.
