摘要： A recording medium having a dummy signal area on at least one side of a recording area is used and information is recorded with a dummy signal added to at least one of the leading and trailing sides in the recorded information signal. The user data area remains unaffected by repeated overwriting so that recorded user data is reproduced correctly. In particular, the wave form distortion caused by fluidization of a recording film remains at the dummy signal area and does not affect the user data area, so that the reproduction of the target information (user data) is assured.

摘要： An optical recording medium includes grooves and lands on a substrate in which prepits are disposed on an extension of the boundary between a groove and a land such that they are located uniformly on both sides of the center line of the groove or the land and that they do not exist on the both sides of any specific position of the center line of the groove or the land. Through this, address data would be obtained with ease and tracking offset would be decreased.

摘要： An information memory apparatus includes an information storage medium having a thin film formed as a recording layer or a superresolution reading mask layer on a substrate directly or via a foundation layer to record and/or reproduce information stored in the form of an atom configuration change caused by irradiation of an energy beam. The information storage medium includes reflective layers as well. The information memory apparatus further includes a laser used for at least recording. The laser has a wavelength. The light absorptance of the recording layer or mask layer of the medium in a crystalline state at the wavelength is greater than or equal to the light absorptance of the recording layer or mask layer of the medium in an amorphous state at the wavelength. The information memory apparatus further includes an optical head control circuit, a tracking error detector, an optical head moving driver, a recording data modulator, a laser driver, a reproduced signal processor and a reproduced data sending unit.
