PART
6: TAPES
by Christina
Fox
At the heart of the recorder
is a rapidly rotating drum, set at an angle, with the recording heads
mounted on it. The tape is wrapped around the drum as it is loaded into
the recorder. As the tape passes across the drum, the heads convert the
electronic video signal from the camera into magnetic pulses and 'write'
the signal onto the tape. Because of the angle of the drum, the video
signal is recorded diagonally across the tape in a helical pattern. The
sound heads are also mounted on the drum and the hi-fi audio signals are
encoded in the picture track.
