Abstract:
A video recording apparatus for recording, to an information table of a magnetic tape, a tape position of bad spots on said magnetic tape, said recording apparatus comprising:recording means having a magnetic head for recording input digital data on the magnetic tape at a normal speed;reproducing means for reproducing said input digital data recorded by said recording means;driving means for driving the magnetic tape;detecting means for detecting an error in data reproduced by said reproducing means indicative of a bad spot on said magnetic tape and outputting an error detection signal representative thereof; andcontrol means for controlling said recording means to record in said information table information indicating said tape position where said detecting means detects said error indicative of a bad spot on said magnetic tape, for controlling said driving means in response to the error detection signal to move the magnetic tape past the magnetic head directly to a search point corresponding to and located after said bad spot in one of a forward direction and a backward direction of tape movement on said magnetic tape without first moving the magnetic tape to the end thereof and then to the beginning thereof and at a speed higher than the normal speed such that dregs are removed from the magnetic head and the magnetic tape as a result of the higher speed movement of the tape past the head, for controlling said driving means in response to the error detection signal to move the magnetic tape in the other of the forward direction and the backward direction of tape movement to a re-recording start position corresponding to said tape position at which the error is detected, and for controlling said recording means in response to the error detection signal to begin a re-recording operation of the input digital data corresponding to the detected error at the re-recording start position.
