| titleOfInvention | Information reproducing device for optical information recording medium |
| abstract | (57) [Summary] (with correction) [PROBLEMS] To provide an information reproducing method for an optical information recording medium capable of continuously maintaining a temperature at which a mask phenomenon can be exhibited without continuously outputting a reproducing laser beam at a high output state. I do. SOLUTION: A recording layer 4 on which information is recorded at a high density, and an optical change by a temperature change so as to substantially reduce an irradiation spot area of a reproduction laser beam 10 irradiated at the time of reproduction while masking the recording layer. In the information reproducing apparatus of an optical information recording medium for reproducing recorded information by irradiating a laser beam for reproduction onto the recording layer through the mask layer to the optical information recording medium having Main laser beam 10A for continuously irradiating a laser beam to form an irradiation area, and auxiliary reproduction laser beam 1 for intermittently irradiating the same area as the irradiation area. 0B, the laser beam for main reproduction and the laser beam for auxiliary reproduction are overlapped to form a high-temperature portion in the irradiation area, and information recorded at high density is reproduced. |
