Abstract

PURPOSE:To stably maintain the rotating speed of a recording medium in either one of a field or a frame recording and to effectively record a picture signal on the recording medium by discriminating the field recording or the frame recording from the picture signal and automatically setting a propriety for executing a skew compensation or not according to a discriminating result. CONSTITUTION:A detecting means 8 for detecting the presence and the absence of the generation of the prescribed quantity of the dislocation of the horizontal synchronizing signal of an input picture signal before and after switching a picture and a switching means SW1 for executing the skew correction 9 of a servo system to a phase dislocation only when the generation of the dislocation of the prescribed quantity of the horizontal synchronizing signal is detected by the detecting means 8 are provided. Thereby, a constantly stable synchronizing signal can be obtained from the picture signal of a field picture and a frame picture to effectively execute the servo control of the recording medium.
