摘要： In the related art, writing of BCA data has been performed by a BCA cutter or the like after a user data area was formed. However, according to such a method, individual steps cannot help being provided for a disc manufacturing step in order to form the BCA. A burden on the disc manufacturer is large from a viewpoint of the number of disc producing steps and, further, manufacturing costs. By using a bit forming method similar to a user data area, the BCA manufacturing steps can be reduced. Specifically speaking, by devising a pit depth, a pit width, and a pit pattern, a modulation degree of a BCA portion can be further increased. A detecting method similar to that for the BCA in the related art can be applied.

摘要： A quick retry operation is possible by outputting an error flag pertaining to a sector after error correction processing of digital data. When an output of an error detection flag unit for a correction block indicates the existence of an uncorrectable error, the sectors are checked to see if the sectors corresponding to retrieved data include any error or not based on output from a sector error flag register B. When the sectors are judged as error, signals are retrieved again from a storage medium, restored in a memory, and an error correction processing is repeated again. The data such as that of P pictures or B pictures of MPEG which can be reproduced even with errors are output even when the error detection flag unit indicates the existence of the uncorrectable error. It enables identification of the sectors with the errors and simplifies the following operations pertaining to the error at a data receiving side by outputting the error flag along with the data.
摘要翻译： 通过在数字数据的纠错处理之后输出与扇区相关的错误标志，可以进行快速重试操作。 当用于校正块的错误检测标志单元的输出指示存在不可校正的错误时，根据来自扇区错误标志寄存器B的输出，检查扇区以查看与检索数据相对应的扇区是否包括任何错误。 当扇区被判断为错误时，再次从存储介质中取回信号，并将其恢复到存储器中，并再次重复纠错处理。 甚至当错误检测标志单元指示存在不可校正的错误时也输出甚至可以再现错误的MPEG图像的P图像或B图像的数据。 它能够识别具有错误的扇区，并通过与数据一起输出错误标志来简化与数据接收侧的错误有关的以下操作。

摘要： A digital data recording/reproducing method includes the steps of: interleaving data on a PI code for each PI code of a 208-row ECC block; and converting a short burst error into random errors by dispersing errors on the PI codes. Moreover, the digital data recording/reproducing method increases correction capability against several bytes to several tens bytes of errors generated at random without changing burst error correction length by performing this processing for respective PI codes by using interleave rules that are different as much as possible from one another.

摘要： A recordable optical disc includes a user area and a management information area. User data is recorded in a physical block used as a single unit, and the space bit map is recorded in the management information area. Integrity verification processing is performed for each of recording status information so as to verify the integrity of the recording status information indicating a recording status of the physical block and the recording status of the physical block on the recordable optical disc. The necessity of the integrity verification processing is determined by reading out the status information indicating the necessity of the integrity verification processing. When the integrity verification processing is determined to be necessary, the integrity verification processing is carried out for unverified recording status information of the recording status information of the space bit map.

摘要： If a large minimum data unit for recorded data is used to record a small data amount of management information, the recording time is long, and furthermore when a WO (write once) is used as the recording medium, the number of recording operations which can be performed is restricted.To solve the above problems, the present invention can record data in a management area in units smaller than ordinary units for recorded data to suitably record information in a limited management area and thereby efficiently use the user data area. At that time, the present invention simplifies interleave processing usually applied to ordinary recorded data, and performs the simplified interleave processing on a data structure (for data of small size) of the present invention so as to ensure the signal processing compatibility between the ordinary data and data having the data structure according to the present invention.
