Abstract
Data read out from a disk is once written in a memory, and data is read out from memory at a rate lower than the writing rate. In a power saving mode, when data in the memory reaches full capacity, the power to a pickup, an RF amplifier, a decoder/signal processing circuit, a servo circuit, and a driver circuit for driving a spindle motor and a sending motor is turned off, thereby temporarily stopping data reading from the disk. Reading from the disk and writing into the memory resumes when power is restored before the memory is completely read out.
