Abstract:
1. An apparatus for recording and reproducing information in which a ring buffer area where an information signal is circulatively recorded and reproduced and a memory area where the information signal is permanently stored are formed on a recording medium, comprising: a memory in which allocation position information indicating the position where said ring buffer area is allocated on said recording medium has been stored; a recording and reproduction controller for performing recording and reproduction of information into/from said ring buffer area based on said allocation position information stored in said memory; an operating component for generating an erasing command signal for erasing the information signal as an erasure target from said information signal recorded in said memory area in accordance with an erasing operation; and a ring buffer area extending component for additionally storing position information of the information signal as said erasure target into said memory in order to set the area where the information signal as said erasure target has been recorded to the ring buffer area in response to said erasing command signal.
