Abstract
Method and apparatus for editing a recorded series of bits on a rewritable disc media. The method includes the steps of selectively identifying a beginning point and an end point of a segment of the recorded series of bits to be deleted; and modifying a first jump command in a control data portion of the disc. The first jump command is modified for causing playback from the disc to continue at the end point when reading in a forward direction. The method can further include modifying a second jump command in a control date portion of the disc for causing playback from the disc to continue at the beginning point when reading data for playback in a reverse direction.
