摘要： In an information recording medium, wherein data are reproduced in a sector unit, a file area for recording the file systems of a plurality of operating systems and a discrimination area for recording the position data on the file systems in the file area are provided. Then, the same data recorded in the recording medium can be managed by the operating systems of different file management systems. In a recording apparatus for reproducing data from the information recording medium, the position data are reproduced from the discrimination area and the data recorded in the information recording medium can be read by converting the position data to an actual sector address in the information recording medium. Thus, a file can by reproduced from the recording medium with either of the operating systems.

摘要： The present invention relates to an information retrieval apparatus for retrieving large quantities of the document files stored in the information recording medium by the successive matched comparison between the character string of a target and the character string in the coded document. When the retrieving result of the document file retrieved in the past is stored within the information recording medium together with the retrieving conditions and the document file is retrieved again with the same retrieving conditions, the information retrieval apparatus of the present invention makes it unnecessary to retrieve the document file itself by the reuse of the past retrieving results if the latest retrieved date and time are newer than the recording date and time of the document file so as to shorten the retrieving time.

摘要： An information recording/reproducing apparatus is suitable for writing on and reading from a rewritable optical disk signals having a time-based continuity attribute such as video signals and audio signals. The optical disk has a plurality of tracks each divided into sectors. The apparatus has a RAM for storing data externally supplied, and first and second address counters for generating addresses for writing into and reading from the RAM, respectively. The apparatus also has a track-jump detector circuit for detecting the occurrence of a track jump of an optical head while the head is writing on the disk. When a track jump is detected, a laser driving circuit stops actuating the head such that the writing operation is halted, and a track-jump address latch circuit stores an address of a track-jump occurring sector. Based on the address stored in the track-jump address latch circuit and a track address where the head is actually is, the head is returned to the sector where the track jump occurred. Then, under control of a CPU, the second address counter again generates addresses at which the RAM stores data which should have been written on the track-jump occurring sector from its leading position. Thus, even if a track jump occurs, information having a time-based continuity attribute is recorded without any data loss.
