Abstract
A magnetic recording/reproducing apparatus is provided which prevents the deterioration of the signal quality when a portion of a signal recorded on successive tracks on the magnetic tape is dubbed (postrecorded).
Claims12
Apparatus for recording an information signal on a magnetic tape, comprising:
- means for receiving said information signal;
- means for transporting said magnetic tape in a transport direction;
- means including a magnetic head for recording a frame of said information signal on N successive tracks on said magnetic tape, wherein N is an integer and wherein a track pitch of each of said tracks is shorter than the width of said magnetic head;
- means for postrecording M tracks of said frame, wherein M is an integer less than N and greater than or equal to 2;
- and
- means for controlling a relative position of said magnetic head with respect to said transport direction of said magnetic tape to inhibit tracks adjacent to said M tracks from being overwritten during the postrecording of said M tracks.
