PURPOSE:To accurately and easily grasp the content of program data on a tape, by preparing an audio tape recording interpretation data of each program data and picking up the interpretation data from a reproduced output as an audio output. CONSTITUTION:A reproduced output of a tape recorder 12 is subjected to attenuation of signal components in 1,200Hz and 2,400Hz at the 1st and 2nd filters 13 and 14. Thus, a reproduced output of program data PDn and PDn+1 is hardly found at an output terminal of the filter 14. The reproduced output of interpretation data RDn and RDn+1 picked up in this way is applied to a speaker 16 to obtain an audio output representing the content at the program data PDn and PDn+1. Thus, the content can easily be grasped. |
