摘要： An information recording and reproducing apparatus includes a rewritable optical disc having a plurality of sectors on which data can be rewritten. The rewritable optical disc is divided into an additionally recordable region in which the data are additionally recorded and a rewritable disc control region in which an address of a latest recorded sector in the additionally recordable region is recorded. The optical disc is used as an additionally recordable optical disc in which recording is permitted only one time and reproduction can be performed plural times. The information recording and reproducing apparatus further includes a control circuit for recording data on unrecorded sectors in the additionally recordable region and for reading the data from recorded sectors. This control circuit can rewrite and reproduce data in the disc control region. The control circuit reads the disc control region prior to additional recording of data, thereby finding a first unrecorded sector from the address of the latest recorded sector recorded in the disc control region. Furthermore, the control circuit records data on unrecorded sectors following the first unrecorded sector, and upon termination of data recording, the address of the latest recorded sector in the disc control region is rewritten.

摘要： In data recording medium used with the apparatus of the present invention, there are allocated a sequential access zone consisting of a data area for recording real time data such as sounds or video images, a C list area for recording a C defect list managing defective sectors detected in the formatting process, and a G list area for recording a G defect list managing defective sectors detected in the recording process of data, and a random access zone consisting of a data area for recording random access data such as code data, a spare area for replacing defective sectors detected in the recording process, and an R list area for recording an R defect list managing the relation between defective sectors and corresponding spare sectors. In the recording process of data in the sequential access zone, data is recorded while defective sectors registered in the C defect list and G defect list are skipped, thereby achieving recording of both the random access data and the real time data. Moreover, sequential reproduction of real time data is realized.

摘要： A read only optical disk is provided which includes (1) information sectors having recorded therein first encoded data obtained by encoding data by a first error detection/correction code to perform error detection and correction of the data and (2) check sectors each having recorded therein second encoded data obtained by encoding data among the first encoded data recorded in a plurality of selected information sectors by a second error detection/correction code. The second encoding by the second error detection/correction code is performed with respect to the data of the plurality of selected information sectors which are selected from respective tracks and are arranged sequentially at predetermined intervals in the circumferential direction on the tracks. As a result, in this read only optical disk, even when a two-dimensional defect (i.e., one extending circumferentially and radially) is present on the disk, there is no case in which two or more information sectors associated with the check sector cannot be subjected to error correction. Also, as a result of having one track including (2.sup.m -1) information sectors and one check sector which has overall parities of the information sectors recorded therein, it becomes possible to record in the check sector and in each of the information sectors, respectively, an address, which is peculiar to each sector, to thereby, realize the reproduction of data with high reliability.

摘要： Directory data relating to user data are recorded in sectors of a checkerboard pattern or in sectors on every other track in a directory data area on an optical disk. The sectors which store the directory data are always flanked by adjacent virgin sectors in a direction normal to the tracks. Therefore, the latest directory data can be detected highly reliably without crosstalk noise from adjacent tracks. Alternatively, old directory data except the latest directory data are deleted or old directory data except the latest directory data and directory data in a predetermined number of sectors before the latest directory data are deleted, and the latest directory data can be detected highly reliably by detecting the deletion of the directory data.

摘要： An optical information recording and reproducing apparatus irradiates a laser beam to an optical disk for repeatedly recording and reproducing data on and from data sectors of the optical disk. The optical disk comprises a plurality of track blocks each comprising data sectors for recording data thereon, alternate sectors for substituting defective ones of the data sectors, and at least one mapping sector for recording mapping data representing the address correspondence between the defective sectors and the alternate sectors substituting the defective sectors. The optical information recording and reproducing apparatus comprises a recording and reproducing circuit for recording and reproducing data on and from the data sectors, an error control circuit for correcting an error occurred in any one of data, a defective sector detecting circuit for detecting a defective sector, a memory for storing mapping data, and a sector substituting circuit for substituting a defective sector by one of the alternate sectors. Mapping data representing the correspondence between the address information of the defective sector and that of the alternate sector substituting the defective sector is recorded on the mapping sector in the same block, and, at the time of data reproduction or data re-writing, the address information of the alternate sector is detected from the mapping sector of the block to which the alternate sector belongs, so that the data can be reproduced from or re-written on the alternate sector at a high speed.

摘要： An optical recording and reproducing apparatus for recording and reproducing data in an optical disk is disclosed. The optical disk has a plurality of erase test sectors in tracks, in one of which the accumulated number of tests together with test data is written. The data read from the erase test sector is compared with the recorded data to effect an erase function diagnosis. If data comparison shows an non-coincidence or the accumulated number of tests exceeds a predetermined value, a new erase test sector is used. The fatigue of the recording medium caused by a defect of the medium or reduced erasing efficiency due to an increased number of erasures of the recording medium is checked by controlling the accumulated number, completely separately from the fault of erase function of the apparatus, thus improving the reliability of the erase function self-diagnosis. Upon detection of an error in the read data or when the accumulated number of tests exceeds a predetermined value, a marking signal is written in the data field of a defective sector, and the apparatus shift to a new erase test sector not yet marked for subsequent erase function self-diagnosis, thereby making possible erase function self-diagnosis without being affected by the fatigue of the recording medium.
