ABSTRACT:
A digital video tape recording method for trick play includes the steps of dividing the data area of a video sector of respective tracks of the digital video tape into first, second and third regions, interspersely recording normal play data and trick play data in the first and third regions, and recording the normal play data in the second region, wherein the trick play data recorded in the first and third regions is frame data corresponding to the maximum odd-fold speed of a plurality of given odd-fold speeds, and the same trick play data is repeatedly recorded for a number of tracks equal to twice the number of the maximum odd-fold speed, thereby enabling satisfactory trick play at various odd-fold speeds and with various scanners.
