ABSTRACT:
When a transport packet of the MPEG2 signal is recorded, a tape speed is reduced to 1/2 or 1/4 of that used to record standard data in accordance with the bit rate of the program. Two heads (A and B) having different azimuths are provided in close proximity with each other at the same height on a drum. If the 1/2 tape speed mode is selected, the recording is performed by head A during the first scan of the tape and by head B during the next scan. Even when the tape speed is a fraction of an even number of the standard tape speed, the azimuth angles of adjacent tracks are different and azimuth recording is performed to reduce crosstalk.
