ABSTRACT:
A method and apparatus for recording and reproducing a video signal which enables the provision of a VTR which is reduced in noise, lowered in power consumption, and can be used at a high magnetic permeability, wherein the diameter of the rotary drum and the wrap angle of the magnetic tape on the rotary drum are left unchanged, but the rotational speed of the rotary drum is halved and the number of magnetic heads disposed at the rotary drum are doubled and recording is performed by time expansion by a factor of k of the recording data rate of the video signal. Since the rotational speed of the rotary drum is halved, the noise is reduced and the power consumed by the motor and the rest of the drive system for driving the rotation of the rotary drum is lowered. In addition, the recording data rate is lowered, so use may be made of magnetic heads with high magnetic permeability characteristics.
