Recording and/or reproduction apparatus capable of retaining start up information |
摘要 |
A recording and/or reproducing apparatus in which a head is driven along a disk while the disc is rotated. A rotation speed control and a rotation phase control are provided to control the disc rotation. The apparatus is operated in a phase control mode until the phase of the disc rotation deviates from a reference phase by a predetermined amount. Then the apparatus switches to speed control. A memory is used to store data concerning start up information to reduce the required amount of start up time required in future operations.
