摘要:
An information recording medium (100) includes: a first recording layer (107); a semitransparent reflective film (108) to reflect at least one portion of laser light for recording with which the first recording layer is irradiated; a second recording layer (207) which is irradiated with the laser light for recording through the first recording layer and the semitransparent reflective film; and a reflective film (208) to reflect the laser light for recording with which the second recording layer is irradiated, thermal conductivity from the second recording layer to the reflective film when the second recording layer is irradiated with the laser light for recording being substantially equal to thermal conductivity from the first recording layer to the semitransparent reflective film when the first recording layer is irradiated with the laser light for recording
摘要:
There is provided an information recording medium having a plurality of recording layers (layer L0, layer L1) for recording information. At least one of the recording layers (layer L0, layer L1) has a management information area where recording speed management information defining the maximum possible recording speed when recording information is recorded.
摘要:
An optical recording medium, in which a first substrate, a first recording layer, a first reflecting layer, an intermediate layer, a second recording layer, a second reflecting layer, and a second substrate are at least laminated, the optical recording medium further including a transcription layer between the second recording layer and the second reflecting layer. The optical recording medium of the invention can solve a problem of insufficient signal amplitude of one recording layer as compared with the other recording layer in a writable optical recording medium of a conventional double layer structure.

摘要:
An optical recording medium of dual layer type is provided which has at least a first substrate, a first recording layer capable of optical recording, a translucent reflecting layer, an intermediate layer, a second recording layer capable of optical recording, and a second substrate in this order from a side where a laser beam for recording, reproduction, or recording/reproduction is applied, wherein the first recording layer is made of an organic dye and the second recording layer is made of a metal material having a higher reflectivity than the organic dye. The optical recording medium provides sufficient signal amplitudes from both recording layers during reproduction, and gives compatibility with a typical optical recording medium during reading.
