Filed: 1985-11-08
Abstract: PURPOSE:To make special reproduction of video signals recorded by CLV (fixed angular velocity) system free from disorder possible by storing video signals once in a recording means and controlling writing and reading according to control information at the time of special reproduction. CONSTITUTION:When reproducing at double speed, control signals are given from a reproduction control section 2 and jump between tracks of a laser spot and CLV rotation are controlled to make reproducing of F7, F8 fields possible, and tracing is performed.

At the same time, a write control section 8 outputs a control signal 52 to a memory section 7 to prohibit writing of reproduction signals. Consequently, signals of 'H' are inputted to the memory section 7 until F7 is reproduces as shown by waveform 52, and writing operation is prohibited. Output of the memory section 7 becomes continuous reproduction output F7, F8 as waveform 53.
