ABSTRACT:
An information processing apparatus for effecting the erasure of information recorded on a recording medium has wide area erasing means for erasing the recording information of a wide area recorded on the recording medium, and narrow area erasing means for erasing the recorded information of a relatively narrow area as compared with the wide area erasing means. The wide area erasing means and the narrow area erasing means are used together to erase a desired range of recorded information.
