Abstract

PURPOSE:To improve variable-speed reproduction characteristics by providing rotary heads successively and by using them by switching. CONSTITUTION:Records on tracks 41, 42... recorded on magnetic tape 40 are provided successively being shifted as much as one horizontal scan and tracked by rotary heads 2 and 3, which move to position 2' and 2'' and then to 3' and 3''. When records are reproduced by using head 2 up to position 2' and then head 3 by changing over the switch, record on track 41 are completely tracked in variable-speed reproduction such as still reproduction. As a result, variable-speed reproduction characteristics of still reproduction, etc., improve.
