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： The optical recording medium has sandwiched between protective layers a mask layer whose refractive index is changed in one part within a light spot when irradiated with a laser beam of 2 to 4 mW. In a region where the refractive index is changed or in other remaining regions, the difference in the amount of reflected light between the crystalline state and the amorphous state is so small that a reproduced signal is difficult to identify. By reducing the size of a portion where the reproduced signal can be seen, it is possible to read high-density recorded information.

摘要： An information recording and reproducing apparatus that prevents an information recording medium from being taken out of its cartridge inadvertently. The information recording medium allows recording information thereon by irradiation of an energy beam. The cartridge comprises a body and a cap adapted to a separable from the body or opened/closed thereon. An information recording medium is accommodated in the cartridge to allow recording and reproducing of information by irradiation of the energy beam. The cartridge also has locking member for fixing the body and the cap together in a closed state. If the information recording medium needs to be taken out of the cartridge after the same has been set on the recording and reproducing apparatus, the locking member is released to make the cap separable from the body or open on the body and the cartridge is ejected from the recording and reproducing apparatus.
