Abstract

PURPOSE: To speed up the titled device by writing information in a recording medium in parallel completely independently of a host computer at the tie of recording, and at the time of reproducing, transferring data in a cache memory to a host computer.
CONSTITUTION: Information is registered in a 2nd storage device 104 by a control device 107 and an information input device 105 and an address is registered in a 1st storage device 103. Then, information corresponding to an address newly registered in the device 103 or an updated address is transferred from the 2nd storage device 104 to an optical signal recording and reproducing body 101 and stored in the medium. At the time of requesting reproducing, a computer 108 specifies the address to be reproduced, and when the specified address has been already registered in the 1st storage device 103, the control device 107 transfers the information corresponding to the address from the 2nd storage device 104 to the computer 108 through an information output device 106. When the address is not registered yet, the information corresponding to the address is reproduced from the body 101 and stored in the 2nd storage device 104 and the address is newly registered in the 1st storage device 103.
