    摘要: An information recording/reproducing apparatus for recording or reproducing information on or from a recording medium in response to a command sent from a host computer has a cache memory serving as an intermediate memory and temporarily storing information to be transferred to or from the host computer. In response to an information record command sent from the host computer, completion of writing of information is reported to the host computer at the end of storing record data transferred from the host computer in the cache memory. The record data stored in the cache memory is written on a recording medium independently of data transfer between the host computer and intermediate memory. In response to an information playback command sent from the host computer, it is determined whether playback data requested by the host computer is consistent with unprocessed record data stored in the cache memory. When the playback data is inconsistent with or no duplicate of the unprocessed record data, writing of data from the cache memory onto the recording medium is suspended and processing requested with the information playback command is executed as a top priority.
