Abstract
A recording/reproducing apparatus using an IC memory, comprising: an IC memory to/from which writing/reading of an audio signal is performed; and a control circuit for controlling writing/reading of the audio signal to/from this IC memory, and its address, and controlling, on writing and reading the audio signal to and from the IC memory, so that its address becomes ring-shaped, writing, when a recording key is pressed, the audio signal from an address contiguous to an area, within the IC memory, where the writing, which has never been read after the writing, is performed, and reading, when a reproduction key is pressed, the audio signal from the head of an area, within the IC memory, where the writing, which has never been read after the writing, is performed.
Claims10
A recording/reproducing apparatus, comprising:
- memory means capable of storing a plurality of audio signals, wherein memory addresses within said memory means are arranged in a ring shape;
- control means for reproducing starting at a head address of an area storing unreproduced audio signals in said memory means in response to a reproducing command by a user, and for recording inputted audio signals from a memory address contiguous to said an area in response to a recording command by said user,
- wherein said control means stops said reproducing of said audio signals when said reproducing of said audio signals from said area of said memory means is completed;
- and
- an other memory means for storing a management table so as to manage said memory addresses within said memory means at respective divided areas, wherein said management table includes for each of said respective divided areas:
- a head address of said divided area,
- a head flag for indicating that said divided area is a first area for said writing of said inputted audio signals, and an unreproducing flag for indicating whether said divided area has been reproduced.
