Information recording system

Abstract

Abstract PURPOSE:To re-constitute so that a non-recorded section cannot be included on the way in the sequence from a relatively preceding section by operating a recording information saving means, an erasing means and an information re-recording means repeatedly in a prescribed sequence at the time of the necessity. CONSTITUTION:A magnetic head 12 executes the reading action of information with a command from a keyboard 44, the information is given through a pre- amplifier 14 to an empty track detecting circuit 40, the circuit 40 distinguishes whether the track is not recorded or already recorded and inputs it to a system controller 42. The controller 42 reads information (5) to position immediately after the non-recorded section and stores it to a field memory 26. The information (5) is read from a disk 10, the said track is erased and next, the information (5) is stored into the non-recorded section. Next, the controller 42 distinguishes whether or not the already recorded section is remained after the non-recorded section or the non-recorded section column at said time point, and when it is judged that the section is remained, the action is repeated and when it is judged that the already recorded section is not remained, the action is completed.
