摘要： Methods for updating and recovering user data of a non-volatile memory array such as a flash memory are disclosed. An indication for indicating a mapping relationship for a logical address is established when original user data of the logical addresses is updated into new user data. The indication records new pointers, which record the mapping relationships between logical addresses and physical addresses storing the new user data of the logical addresses. Alternatively, the indication records memory positions of the non-volatile memory array which are defined as designated memory positions and a sequence for using these designated memory positions.

摘要： A data replacement processing method is disclosed. In the present invention, buffering and decoding are not interrupted when a data block to be replaced is found. The data block to be replaced can be a defect or a remapped block. The data block to be replaced is not processed until it is requested to be transferred. When the data block to be replaced is to be transferred, transferring is stopped and the data block to be replaced is processed. Therefore, efficiency of the optical disc drive can be promoted since interruption number of the buffering and decoding is decreased. In addition, the optical disc will not execute redundant processing for data blocks to be replaced which are not requested to be transferred.
摘要翻译：公开了一种数据替换处理方法。在本发明中，当发现要更换的数据块时，不会中断缓冲和解码。要更换的数据块可能是缺陷或重新映射的块。要更换的数据块在被请求传送之前不被处理。当要更换的数据块要传送时，传送停止，并且要更换的数据块被处理。因此，由于缓冲和解码的中断数量减少，因此可以提高光盘驱动器的效率。此外，光盘不会对不被请求传送的要替换的数据块执行冗余处理。

摘要： A method and device for management of defects in a recording medium such as a DVD disc are disclosed. The present invention utilizes defect processing table to reduce the seek times of a pick-up head in obtaining replacement ECC blocks for defect ECC blocks in a user data area of the disc. The defect processing table is used to indicate a location to access replacement block for a defect block. Since the defect processing table (DPT) stores only the relevant information about the defect block and replacement block rather than the defect block or the replacement block per se, it only needs a very small memory space. The present invention also provides a DPT management unit to manage the contents of the DPT.

摘要： The present invention discloses a tilt adjustment system and method of an optical disk device with a pickup head, which includes a decoder for decoding the encoded information from an optical disk and checking whether error occurs during decoding. A decoding error calculator calculates a statistics corresponding to the decoding errors under the different tilts of the pickup head. A tilt control unit utilizes a specific algorithm to determine a decoding error rate, which is minimal than the other error rates within the statistics. Thus, an optimal tilt value can be decided upon the minimal error rate to adjust the tilt of the pickup head.
摘要翻译：本发明公开了一种具有拾取头的光盘装置的倾斜调整系统和方法，包括：解码器，用于对来自光盘的编码信息进行解码，并检查解码期间是否发生错误。解码误差计算器计算与拾取头的不同倾斜下的解码误差相对应的统计量。倾斜控制单元利用特定算法来确定解码错误率，其小于统计中的其他错误率。因此，可以根据最小误差率来确定最佳倾斜值，以调节拾取头的倾斜度。
