PURPOSE:To recognize a proper residual quantity at each recording mode by calculating number of times and quantity making it possible for recording with respect to an unrecorded magnetic track based on the directory and displaying the result of calculation on a display means. CONSTITUTION:When a floppy 51 is set to a camera, it is detected by a switch 74 and a prescribed control signal is fed from a system controller 60 to a controller 59. Thus, a drive voltage is supplied from the controller 59 to a motor 58, the track position of the head 31 is sought sequentially and each track is reproduced by the head 31. The reproducing signal is fed to a detection circuit 43 via a switch circuit 35 and a reproducing amplifier 42 to detect the presence of a recording signal Sv or an FM signal Sf. The detection output is fed to the system controller 60 to generate the directory representing whether the signals Sv,Sf are recorded. Based on the directory, the number of times and quantity making it possible for recording are calculated to the unrecorded magnetic track and the result is displayed on the display means 81.
