ABSTRACT:
The present invention is concerned with a magnetic recording apparatus, such as a video tape recorder, in which the recording circuit, provided with an amplifier connected to a magnetic head, is provided on the side of a rotary head drum. The record control signals for controlling the recording circuit are indicated by serial data and data enable signals indicating the data start and data end points of the serial data. The edge pulses of sync clocks of the serial data are gated by the data enable signals and connected to the serial data, and the transmission mode signals indicating the start and the end of the transmission are further annexed to serial transmission data to form serial control signals, which are then serially transmitted as record control signals from outside of the rotary head drum to the side of the rotary head drum from outside the rotary head drum for simplifying the transmission system for the record control signals.
