Abstract
An apparatus for selectively recording a baseband signal and a MUSE signal on a magnetic tape and for reproducing them at different speeds including: a magnetic head circuit having first and second groups of heads provided separately form each other. Each of the head groups includes four rotary heads for consecutively and helically scanning the tape to record and reproduce the baseband and MUSE signals. The apparatus further includes: an apparatus for providing a mode designating signal for designating an operational mode of the apparatus; a signal processing circuit which can process the baseband and MUSE signals, in response to the mode designating signal, for processing one of the baseband and MUSE signals; a head switching circuit for switching the connection between the signal processing circuit and the respective rotary heads in response to the mode designating signal; and a scanning speed adjusting circuit for adjusting the relative scanning speed of the rotary head and the recording tape in response to the mode designating signal. The apparatus can appropriately switch the scanning speed and the connection between the rotary heads and the signal processing circuit according to the type of signal and operational mode. Thus, the baseband signal is recorded as a two channel signal on the magnetic tape and the MUSE signal is recorded as a one channel signal. Also, the apparatus can reproduce the baseband and MUSE signals recorded according to the above-described track pattern at a different speeds, respectively.
