Abstract
PURPOSE:To lower the driving speed of a recording medium, and to extend recording time longer by separating only one side of field video signals, and recording it as extending its time base. CONSTITUTION:A field video signal separating means 13 to separate one of two field signals constituting a video signal from the other, and a time base extending means 14 to extend the time base of the separated field signal are provided. Besides, a driving means 18 to lower the driving speed according to the degree of extension of the time base at the time of recording and reproducing, and a time base compressing means 24 to compress the time base of the reproduced field video signal, and an interpolating means 25 to interpolate the field video signal of an unrecorded side based on the time base compressed field video signal are provided. Thus, the quantity of information is reduced nearly to half by separating the field video signal of one side, and a signal band is compressed by extending the time base of the field video signal, and in company with this, the carrier frequency of a modulated signal is lowered, and long time recording can be realized as keeping a recording density.
