Abstract

PURPOSE: To reduce greatly the skew in rapid reproduction, slow reproduction and still reproduction by recording tracks while adjacent synchronous tracks are shifted by KH (horizontal synchronous intervals)/2 and every other track agrees.
CONSTITUTION: Alternate one-field video signals are recorded on recording tracks 1, 3 and 5 by a recording head of channel (a) and on recording tracks 2 and 4 by a b-channel recording head being given an azimuth mutually. Adjoining synchronous tracks 6 and 7 are recorded being shifted by KH/2 and tracks 1, 3 and 5, namely, tracks recorded by the a-channel magnetic head are recorded with synchronous tracks aligned. Similarly, tracks 2 and 4 are recorded. Consequently, when signals are recorded at a variable tape speed, the number of kinds of tape speeds where no skew is caused in fast reproduction, still reproduction and slow reproduction is twice as much as before.
