摘要：
This invention provides a disk playback apparatus which can shorten a time from when a power switch is turned on until a startup operation is completed. Even when the power switch of the main body is OFF, if exchange of a disk-like recording medium is detected, management data of the disk is read out and is stored in a buffer memory. When the power switch is turned on for the next time, the management data is read out from the buffer memory without accessing the disk-like recording medium.
