    摘要： In a process for producing optical disks comprising the steps of subjecting the photoresist layer (3) on a substrate (1) formed of silicon, quartz, glass or a metal to light exposure, developing and etching treatments to obtain a stamper (6) and then duplicating an information pattern for an optical disk from the stamper (6) obtained above to a transparent substrate by using a UV curable resin to prepare a replicated substrate of an optical disk, a large number of stampers (6) can be prepared in a short time by conducting the light exposure (7) either by contacting the mask side surface of a substrate (1) provided with a photomask having an information pattern for an optical disk to the photoresist side surface of said substrate having the photoresist layer (3) or by noncontact projection, and a rapid replication of large quantities of replicated substrates becomes possible by using a large number of stampers (6) thus prepared.

    摘要： A recording medium has a substrate 1 and formed thereon an inorganic material layer 2 adapted to absorb light to generate heat and an organic material recording layer 4 adapted to be deformed or removed by the heat. To give the recording medium stability against changes in ambient temperature, an intermediate layer 3 is located between the inorganic material layer 2 and the recording layer 4. The intermediate layer is made of an organic material containing metal, e.g. a metal salt of an organic acid, an organometallic compound, etc.

    摘要： System in which a phase transition type recording film (2) is used as an information recording medium, and for recording information, a focused electron beam is selectively projected on desired positions of the recording film so as to locally heat the recording film and cause phase transition, while for retrieving information, an electron beam having energy at a degree not causing the phase transition is projected so as to utilize the fact that reflection or diffraction (7) of the primary electron beam (6) projected at the retrieval differs between the recorded regions (22a, 22b) and unrecorded regions (21a, 21b, 21c).
