Filed: 1992-09-03
Abstract: PURPOSE:To prevent recorded data from being destroyed by track jump and to efficiently execute a re-recording operation by speedily detecting the track jump, immediately stopping a data recording operation and performing re- recording by using prescribed data recorded in a buffer memory. CONSTITUTION:At the time of the recording operation, a system controller 11 searches an unrecorded area corresponding to the data of a TOC 21 according to the operation of an input part 19 by user, provides guard bands GB before and behind the area and starts recording through a RAM 13. At such a time, when the count value of a traverse signal in a servo circuit 9 exceeds a prescribed value, the generation of the track jump is judged, and the recording operation is immediately stopped. Then, an absolute position after the track jump is detected, and a position to start re-recording is judged. Thus, the recorded data are surely prevented from being destroyed, and data recovery processing can be efficiently performed.

The electrode of the solar cell is not deteriorated by corrosion, due to water vapor contained in the air and excels in durability. Thus, electric resistance does not increase, and the conversion efficiency of the solar cell does not deteriorate. Therefore, the conversion efficiency as a solar cell module also does not deteriorate.
