Abstract

PURPOSE:To share a control program without modifying it even if a top address in an area capable of writing information is changed by making a logical address showing a user data recording area or the difference between physical and logical addresses into a format. CONSTITUTION:An address part 1 is constructed with a physical address part 4 including physical address information showing an absolute address in a recording area, a logical address part 5 including logical address information showing the recording area of user data and a sector mark 3 used for reading an address. After the sector mark 3 is detected, an optical information recording and reproducing device reads the physical address 4 and the logical address 5, and records and reproduces data. In terms of recording and reproducing the user data, the read-out logical address is used, whereby the modification of the control program of the device is unnecessary even if the user data area such as the format of the optical disk and its size is modified.

ることになる。Problems to be Solved by the Invention However, conventional optical discs have a drawback in that the starting address for writing user data changes when the format of the optical disc is changed or the size of the optical disc is changed. Therefore, every time the start address is changed, the recording/reproducing apparatus is forced to change the control program in order to read data from the optical disc.

な光情報記録媒体を提供するものである。The present invention solves the conventional problems, and even if the starting address of the area where information (data) can be written in an optical information recording medium is changed, the control program for reading data is changed. The purpose of this invention is to provide an optical information recording medium that can be shared without any problems.

可能となる。According to the above-described structure, even if the starting address of the user data area is changed due to changes in the format, size, etc. of the optical disc, the control program in the optical information recording/reproducing device can be updated by simply searching the logical address part. It becomes possible to recognize the starting address of the user data area without changing the data area.

ない。FIG. 1 shows the structure of the address section 1 in the first embodiment. The address section 1 includes a physical address section 4 containing physical address information indicating the absolute address of the recording area. and a logical address section 6 containing logical address information indicating the recording area of user data. and a sector mark 3 for reading the address. After detecting the sector mark 3, an optical information recording/reproducing device (not shown) reads the physical address 4 and the logical address 6 to record and reproduce data. In recording and reproducing user data, by using the read logical addresses, there is no need to change the control program of the device even if the user data area is changed due to formatting, size change, etc. of the optical disc.

次に本発明の第２の実施例について説明する。Next, a second embodiment of the present invention will be described.

Even in such cases, by formatting the address section of the guide track not only as a physical address but also as a logical address or an offset amount that is the difference between the physical address and the logical address, the same control program can be used in the optical information recording/reproducing device. This makes it possible to provide compatibility of optical information recording media in optical information recording and reproducing devices.
