Abstract
When a disk unloading operation is made by mistake or when recording is suddenly required after the unloading operation in a conventional disk recording/playback apparatus which has no cancel function of the disk unloading operation, an important recording chance is often missed. This invention allows the user to cancel the disk unloading operation, and can quickly restore the state before the disk unloading operation, thus solving the above problem.
