PROBLEM TO BE SOLVED: To reduce consumption of a battery and to use the battery for a long time by stopping a disk rotating drive means and an optical head servo means after reading out TOC(table of contents) information from a disk recorded with the TOC information and data. SOLUTION: When it is detected by a system controller 20 that a power-on/off switch 5 is turned on, an optical head 23 is brought into a read-in position of the disk 15 by driving a feed servo circuit 26, and a focus/tracking servo circuit 25 is also driven for the purpose of reading the TOC information, and simultaneously, a spindle servo circuit 22 is also driven to start up the disk CDM(compact disk-interactive media) 15. Subsequently, upon completion of reading the TOC information from the disk CDM 15, the spindle servo circuit 22, the focus/tracking servo circuit 25 and the feed servo circuit 26, etc., are stopped. Thus, by stopping the driving circuit of the disk CDM 15, useless consumption of the battery is prevented. |
