摘要: A disk reproducing apparatus is provided which can cope with the intermittent access due to track jump in the conventional CD reproducing system and which can reproduce data at N times the normal speed and produce the reproduced data at the normal speed. The disk reproducing apparatus includes a memory (11) for storing the data and time information reproduced from the disk to match with each other, another external memory (15), a detection circuit (10) detecting the time difference between the finally produced output data and the data which is being accessed, and a control circuit (19) detecting the overflow/underflow of the external memory (15) and controlling it to be written. The construction can absorb the time difference between the system operation speed and data output speed even during an intermittent access so that continuous data can be produced.
