ABSTRACT:
An information recording and reproducing apparatus includes a record merge buffer which stores blocks of data bound for a disk. A write back mechanism stores blocks of data in the record merge buffer and reports to a host device that a recording operation is complete. A write merge mechanism writes new data that is continuous with data that is being recorded on the disk in the record merge buffer while continuing the recording operation such that the new data is continuous with the data being recorded and is written to the disk in the same recording operation. A write queue management mechanism writes new data that is not continuous with the data being recorded on the disk in the record merge buffer such that the new data is recorded in the record merge buffer at a distance from the data being recorded to the disk that is the same as the distance on the recording medium between the data. When the recording operation is complete, a queue back transition mechanism ensures that record pending data is recorded to the disk.
