METHOD AND DEVICE FOR EXECUTING PATTERNED READ/WRITE OPERATION

摘要

PROBLEM TO BE SOLVED: To minimize waiting time and to execute interleaved read and write by writing the pattern of a data unit separated by a gap in 1st and 2nd operation modes to a recordable media and writing a new data unit to the gap in the short seek of read data. SOLUTION: A host processor 16 is operated by an instruction of a driver 12 and writes a data unit separated by a gap to a disk 10 using a read/write DVD drive 22 in a 1st operation mode. The processor 16 makes the drive 22 read the data unit separated by the gap in a 2nd operation mode. The processor 16 makes the gap write the data unit to a computer 14 in short seek of the data unit read by the drive 22 in the 2nd operation mode.
