IPC: G11B7/125
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To use cooling due to radiation in addition to cooling due to conduction with a large ratio and to efficiently discharge heat from a light source by reducing the size of a light source mount part for placing the light source with a large calorific value for increasing temperature. SOLUTION: A light source 2 on a light source mount part 1f has a wavelength of 650 nm and is used for recording and reproducing a high-density optical disk, while a light source on a light source mount part 8f has a wavelength of 780 and is used for reproducing a low-density optical disk. There is a level difference in radiation property being requested between the light source mount part 1 for placing the light source 2 that may be used with an output of 20 W or larger on recording and the light source mount part 8 for mounting a light source that is used with an output of only several mW on reproduction. Therefore, the size of the light source mount part 1f is reduced as compared with the light source mount part 8f, thus increasing the temperature of the light source mount part 1f and hence increasing the temperature difference from a surrounding atmosphere.  Since radiation heat is proportional to the power of four of the temperature difference, the ratio of cooling due to radiation increases as compared with the cooling due to conduction.
