    • Method for controlling information recording in an information recording apparatus which includes a rewritable information record medium containing a data record area having a plurality of data recording blocks and an alternative area in which data to be written into a defective block in the data record area is written, and writing and reading of data to and from the blocks and erasing of data may be carried out, wherein, data is written into the respective blocks in the data record area on the information record medium, and if a data record error is detected, data to be written into the defect block is written into a block of the alternative area. When data is subsequently rewritten, contents of all blocks in the data record area to be rewritten, including the block previously determined to be defective, are erased and the new data is rewritten, and the content of the alternative area is erased. If a data record error is detected after rewriting, the data to be written into the defect block is written into a block in the alternative area.
    • 一种用于控制信息记录装置中的信息记录的方法,该信息记录装置包括可重写信息记录介质,该可重写信息记录介质包含具有多个数据记录块的数据记录区域和写入数据记录区域中的缺陷块的数据被写入的备用区域 并且可以执行将数据写入数据和从数据块读取和擦除数据,其中数据被写入信息记录介质上的数据记录区域中的各个块,并且如果检测到数据记录错误, 要写入缺陷块的数据被写入替代区域的块中。 当随后重写数据时,将要重新写入的数据记录区域中的所有块的内容(包括先前确定为有缺陷的块)的内容被擦除,并且重写新的数据,并且擦除替代区域的内容。 如果在重写后检测到数据记录错误,则要写入缺陷块的数据被写入替代区域中的块。

    • A data recording/reproducing method for a non-rewritable recording medium of a rotating type, each of tracks on the recording medium is divided into a plurality of blocks which are allotted with respective addresses. Each block includes a data recording area and a deletion flag area which is divided into a plurality of sub-areas. One of the sub-areas in a given block is associated with other block which is in a predetermined address relation with the given block. When the content in the data recording area of one block on the recording medium is to be rendered invalid, deletion flag information is also recorded in the sub-area of the other block having the predetermined address relation with the one block. Upon reading, the data of the blocks read out from the recording medium exclusive of the data of the block determined to be invalid on the basis of the flag information is transferred to a high-rank system.
    • 用于旋转型不可重写记录介质的数据记录/再现方法,记录介质上的每个磁道被分成多个分配有相应地址的块。 每个块包括被划分成多个子区域的数据记录区域和删除标志区域。 给定块中的一个子区域与与给定块处于预定地址关系的其他块相关联。 当记录介质上的一个块的数据记录区域中的内容将被无效时,删除标志信息也被记录在具有与该块的预定地址关系的另一个块的子区域中。 在读取时,除了基于标志信息确定为无效的块的数据之外,从记录介质读出的块的数据被传送到高等级系统。

    • Disclosed is a control method for writing or reading sequentially a plurality of blocks of data for a storage device using a recording medium, such as a photo disk, with a number of recording blocks each having a unique address. In writing data, a plurality of data blocks to be written concurrently are given in their pointer fields the first address indicating the same alternative block, and these data are written in consecutive recording blocks on the recording medium. If blocks with write errors are detected, the data blocks corresponding to the error blocks are written sequentially in an alternative area starting from the first address, after replacing the pointer fields with the second address indicating the defective blocks, respectively. This allows the access of the alternative blocks for defective blocks by detecting the pointer address within the pointer fields of normal blocks preceding and following each of the defective blocks during the data reading operation.
    • 公开了一种用于使用诸如光盘的记录介质来顺序地写入或读取用于存储设备的多个数据块的控制方法,其中多个记录块具有唯一的地址。 在写入数据时,在其指针字段中给出要同时写入的多个数据块,指示相同替代块的第一地址,并且这些数据被写入记录介质上的连续记录块中。 如果检测到具有写错误的块,则在分别用指示缺陷块的第二地址替换指针字段之后,将与错误块相对应的数据块顺序地写入从第一地址开始的替代区域中。 这允许通过在数据读取操作期间检测在每个缺陷块之前和之后的正常块的指针字段内的指针地址来访问缺陷块的替代块。
