摘要： In a track offset adjusting method of an information recording medium, data are recorded onto first and second tracks of an information recording medium. No data are recorded on at least one of tracks adjacent to each of the first and second tracks. After the data recording onto the first and second tracks, data are recorded onto the third track adjacent to the inner circumferential side of the first track and onto a fourth track adjacent to the outer circumferential side of the second track. Thereafter, reproduction signal qualities of the first and second tracks are calculated on the basis of reproduction signals obtained by reproducing the data recorded on said first and second tracks. The track offset is adjusted on the basis of the reproduction signal qualities of the first and second tracks.

摘要： An optical disc recording system includes a host apparatus configured to issue commands; and an optical disc recording apparatus configured to carry out a process corresponding to each of the commands, and to reply a response data to the command to the host apparatus. The host apparatus issues a record command as one of the commands to record a record data in an optical disc medium, and an optical disc recording apparatus records the record data in a data area in a predetermined format in response to the record command, wherein the optical disc comprises the data area and a first control data recording area. The optical disc recording apparatus additionally sets each of second control data recording areas in the data area in association with a command from the host apparatus as one of the commands, and a record status control data is recorded in the first or second control data recording area to indicate record status of the record data. At least a part of a second control data recording area associated data with at least one of the second control data recording areas is shared by the host apparatus and the optical disc recording apparatus.
