Title:
VIDEO SIGNAL RECORDING DEVICE
Document Type and Number:
Japanese Patent JPS6015871
Kind Code:
A
Abstract:
PURPOSE:To attain recording with fast rising and to record accurately a track pitch by constituting the device that a recording element is displaced only by a recording element displacement means for a fixed track range at a low speed recording. CONSTITUTION:When a shutter button for low speed recording is operated at an operation section 1, a pulse Ps is extracted, a control signal (u) from a control section 2 is brought into an H level at the first time of the succeeding field period and fed to a ramp waveform generating circuit 37. A ramp waveform signal (v) is extracted from the circuit 37, fed to an actuator 13 via an actuator drive circuit 36 and the actuator 13 is displaced in a prescribed speed. The slope of this signal (v) is set so that the displacement speed of a video head 10 is one track pitch per one revolution of a recording medium 3. In advancing a recording element for a fixed track range at the one shot recording, the element is moved with fast in comparison with a carrying motor such as a pulse motor, and the instant slow shot is attained and the time from the depression of the shutter button until the start of recording is made as short as within one field period, for example.
