Abstract
PURPOSE: To perform skip recording of the fields of video signal by reducing the running speed of a recording medium and making the maximum record-reproducible frequency 1/C of the maximum frequency of the audio signal processed.
CONSTITUTION: As compared to a standard case of straightly recording the continuous audio signal of 100%, the maximum record-reproducible frequency frmax is made 1/C of the maximum frequency fsmax of the audio signal processed by reducing the speed of a recording medium to convert the period of the audio signal C times, thus about 1/C of the audio signal at each segment is recorded. If the period of the audio signal to be reproduced is converted to 1/C times, the high density recording and reproducing of the audio signal become feasible. Such means is effective as the processing means of the audio signal of the case performing so-called skip recording wherein recording is performed by making the speed of the magnetic tape 1/n of the standard speed VN and 1 field is sampled out of the video signal of continuous (n) fields.
