Claim:
A record and reproduction apparatus comprising: a CPU; a memory; a recording medium control unit configured to read out data from a recording medium; a reproduction buffer configured to temporarily store stream data including at least one of image data and audio data out of the data read by the recording medium control unit; a reproduction processing unit configured to decode and reproduce the stream data temporarily stored in the reproduction buffer; and an access control unit configured to control timing by which the access control unit switches between access to the memory and access to the reproduction buffer under the condition that reproduction of the stream data does not break off during the reproduction of the stream data while supervising the state of the reproduction buffer, and to manage the memory and the recording medium control unit in each transaction, wherein the recording medium control unit is further configured to read arbitrary data out of the recording medium based on the timing controlled by the access control unit and to store the read arbitrary data to the memory during the reproduction of the stream data.
