摘要： A disk recording and/or reproducing apparatus comprises external magnetic field generating means for applying an external magnetic field to a given area, of a rotating disk on which information signals are recorded; of a rotating disk; means for moving the external magnetic field generating means toward and away from the disk in response to commencing an operation of recording of the informational signals on the disk; and means for loading the disk on such a position where the informational signal can be recorded. The moving means moves the external magnetic field generating means toward the disk only when the loading operation of the disk by the loading means is completed. Accordingly, contact of the magnetic head with the disk while the disk is not rotated is prevented.
