摘要： Flash memory devices and associated methods are described for controlling data errors in the devices through various forms of decoding, error correction, and wear concentration. To this end, a flash memory device may be partitioned into a plurality of sectors. Data may then be received from, for example, a host processor for storage within the flash memory device. Storage durations of the data are then estimated and the data is stored in the data sectors based on those estimated storage durations.

摘要： A method, apparatus and program storage device for correcting a burst of errors together with a random error using cyclic or shortened cyclic codes is disclosed. The present invention solves the above-described problems by providing a received word to a syndrome register defined by a polynomial of degree n-k, said polynomial generating a cyclic or shortened cyclic code, wherein n is the length and k is the number of information bits in the codeword. The syndrome gets modified each time the received (possibly noisy) word is shifted. The contents of the syndrome register are processed to identify a random error together with an error burst of the received word. Then correction of the random error and the burst is made and a corrected codeword is generated.

摘要： A disk drive has timing marks (TMs) on the disk, that are chosen to reduce the probability of misidentification of a TM in the presence of read errors. The disk drive searches for TMs within a fixed TM search window which extends past the TM on the disk. A TM preferably maximizes the post-shift sliding distance for m post-shifts of the TM pattern, where m corresponds to the TM search window boundary. In this manner, the probability of a misidentification of the TM due to a post-shift having a small distance from the TM pattern is reduced. The TM pattern also provides pre-shift error resistance.
摘要翻译：磁盘驱动器在磁盘上具有定时标记（TM），该定时标记被选择为在存在读取错误的情况下降低TM错误识别的可能性。磁盘驱动器在固定的TM搜索窗口中搜索延伸超过TM上的TM的TM。 TM TM优选地最大化TM模式的m个移位之后的移位后滑动距离，其中m对应于TM搜索窗口边界。以这种方式，由于与TM图案之间的距离较小的移位后的TM的误识别的可能性降低。 TM模式还提供了前移误差电阻。

摘要： A magnetic recording disk drive has head positioning servo sectors with servo sector numbers (SSNs) that are not recorded on the disk. The SSNs are encoded through the use of multiple servo sector types that are arranged in a specific sequence around the data tracks. The different servo sector types are identified by unique types of servo timing marks (STMs), which are used to locate the servo sectors. The SSNs that are used to identify the servo sectors on the track form a set or code of m fixed n-bit patterns. A SSN is determined when the STM types read from n sequential servo sectors match one of the fixed SSN pattems. A set or code of m servo sectors, where each servo sector is identified by a unique SSN pattern having length n, is denoted as an (m,n,d) code, where d is referred to as the minimum Hamming distance of the code. The Hamming distance between two patterns refers to the number of locations that are different between the two pattems.
摘要翻译：磁记录盘驱动器具有磁头定位伺服扇区，伺服扇区号（SSN）不记录在磁盘上。通过使用以数据轨道周围的特定序列排列的多个伺服扇区类型对SSN进行编码。不同的伺服扇区类型由用于定位伺服扇区的唯一类型的伺服定时标记（STM）来识别。用于识别轨道上的伺服扇区的SSN形成m个固定n位模式的集合或代码。当从n个顺序伺服扇区读取的STM类型与固定SSN模式之一匹配时，确定SSN。通过具有长度为n的唯一SSN模式识别每个伺服扇区的m个伺服扇区的集合或码被表示为（m，n，d）码，其中d被称为码的最小汉明距离。两种模式之间的汉明距离是指两种模式之间不同的位置数。

摘要： A method of detecting and correcting reading errors of track identification (TID) of a magnetic data storage disk. The method comprises a means of constructing a encoded TID which is derived from generalized Gray code. The encoded TIDs have a distance of D between the adjacent code words, and a distance of at least 2D between non-adjacent code words within a band of M TIDS. The encoded TIDs can correct up to (D−1)/2 errors. The method also comprises means of encoding and decoding TIDS, and means of detecting and correcting errors with encoded TIDs.

摘要： A method and apparatus for encoding and detecting data which can be represented in a physical array of modules recorded on a medium. Information is encoded in "image-blocks". An image-block comprises a plurality of "sub-blocks". Sub-blocks comprise a plurality of "modules". A module is the smallest unit of information within the image-block. Discrete contiguous portions of each sub-block of an image-block taken together are encoded into an outer codeword. A plurality of these outer codewords are generated and recorded across each sub-block. A portion of the information that is to be recorded within each sub-block is encoded in a plurality of inner error detection and correction codewords, each preferably stored entirely within one corresponding sub-block. Accordingly, small scattered random errors can be corrected locally by using information entirely contained within the sub-block. If a large area within a sub-block is corrupted, the information contained in each other sub-block may be used to reconstruct the data that was recorded in the corrupted sub-block. The inner codewords are "interleaved" to provide a maximum distance between parts of the same codeword.
摘要翻译：用于编码和检测数据的方法和装置，其可以在记录在介质上的模块的物理阵列中表示。信息被编码在“图像块”中。图像块包括多个“子块”。子块包括多个“模块”。模块是图像块内最小的信息单元。一起拍摄的图像块的每个子块的离散连续部分被编码为外部码字。多个这些外部码字被生成并记录在每个子块之间。要被记录在每个子块内的信息的一部分被编码在多个内部错误检测和校正码字中，每个内部错误检测和校正码字优选地完全存储在一个对应的子块内。因此，可以通过使用完全包含在子块内的信息来本地校正小的分散随机误差。如果子块内的大区域被破坏，则可以使用彼此包含的子块中的信息来重建被破坏的子块中记录的数据。内部码字被“交错”以提供相同码字的部分之间的最大距离。
