[Claims for Utility Model Registration] (1) In a device for recording one frame or one field of video signals on a magnetic disk, an erasing signal generating circuit that outputs a high frequency erasing current and a magnetic head are combined with a video signal recording circuit for erasing. and a control circuit that sends the magnetic head to the next track immediately after recording and connects the changeover switch to the erase signal generation circuit, and performs the erase operation in response to a magnetic head feed completion signal from the control circuit. An electronic still image recording apparatus characterized in that the next track is erased by alternating current by connecting a signal generating circuit to the magnetic head for a certain period of time. (2) Gradually reduce the relative speed of the magnetic head and magnetic disk supplied with a high-frequency erasing current having a frequency of a normal recording signal or almost the upper limit of the normal recording signal band and having a larger amplitude than the recording signal. The device according to claim 1 of the utility model registration claim, which performs alternating current cancellation by.
