Abstract

Abstract An magnetic recording apparatus comprises a magnetic tape and an endless magnetic recording medium. The former carries information signals such as auditory teaching materials recorded upon the first track at a predetermined interval and control signals recorded upon the second track. In reproducing the information signals, they are reprinted or transferred upon the endless magnetic recording medium which has the length substantially equal to the length of the information signal record plus the length of the spacing between two adjacent information signals recorded in the first track of the magnetic tape. After the transfer of the information signals from the magnetic tape to the endless recording medium a student may record his imitation upon the endless recording medium. Thus, the information such as teaching materials and imitation recorded upon the endless recording medium may be repetitively reproduced if desired.
