摘要： A method and means for enhancing the error detection and correction capability obtained when a plurality of data byte strings are encoded in a two-level, block-formatted linear code using code word and block-level redundancy. This is accomplished by vector multiplication of N data byte vectors and a nonsingular invertible integration matrix with nonzero minors with order up to B to secure the necessary interleaving among N data byte vectors to form modified data byte vectors. The selected patterns of interleaving ensure single-pass, two-level linear block error correction coding when the modified data vectors are applied to an ECC encoding arrangement. The method and means are parameterized so as to either extend or reduce the number of bursty codewords or subblocks to which the block-level check bytes can be applied. Lastly, a post-encoding process is provided to “deinterleave” or redistribute the computed codewords into modified codewords such that the data vectors and their codeword check bytes are consistently located in the same codeword with the block-level check bytes are distributed among the first-level codewords.

摘要： A “write-squeeze-verify” method is used for verification of the data that has been written in the annular bands of a shingled magnetic recording disk drive. The writing of data along a track overwrites a portion of the previously written track and thus “squeezes” the data of the previously written track to thereby form a “shingled data track” (SDT). The data in each SDT is read back and verified by an error correction check using error correction bits associated with the data written in the SDT, or by comparing the readback data with the data stored in memory. If the data read back is not verified, a write error counter is incremented and a write error frequency is calculated. One or more attempts to write the data can be performed. If the data in the SDT cannot be verified after the attempted rewrite(s), then a “re-try fail” is reported.
摘要翻译： “写挤压验证”方法用于验证已写入带状磁记录磁盘驱动器的环形带中的数据。沿着轨道的数据写入将覆盖先前写入的轨道的一部分，从而“挤压”先前写入的轨道的数据，从而形成“带状数据轨道”（SDT）。每个SDT中的数据通过使用与写入SDT的数据相关联的纠错位的纠错检查来读取和验证，或通过将回读数据与存储在存储器中的数据进行比较。如果数据回读未被验证，则写入错误计数器递增，并计算写入错误频率。可以执行一个或多个写入数据的尝试。如果在尝试重写后无法验证SDT中的数据，则会报告“重试失败”。

摘要： A method and an apparatus encodes and decodes blocks having a predetermined number of sectors of data bytes to detect and correct data bytes in error in each sector of a block. The method and the apparatus generates sector level check bytes for each sector in the block responsive to the data bytes in each sector according to a first level of an error correction code, and generates block level check bytes for a predetermined sector in the block responsive to the sector level check bytes of various sectors, including the predetermined sector, according to at least a second level of the error correction code. The method and apparatus processes the block to detect and correct data bytes in error in each sector within the capability of the sector level check bytes, to detect and correct data bytes in error in the at least two sectors that exceed the correction capability of the sector level check bytes but within the correction capability of the block level check bytes, or to indicate that the data bytes in error in the at least two sectors exceed the correction capability of each of the sector level check bytes and the block level check bytes. The method and apparatus improves signal quality for long streams of information having multiple sequential physical blocks of data bytes, such as audio visual information, with a low check byte overhead while being compatible with conventional 512 data byte sized sectors and conventional single sector error correction code processes.

摘要： A system and method for algebraically correcting errors in complex digitized phase signals from a magneto-resistive or giant magneto-resistive (MR/GMR) head readback waveform includes a data state machine that encodes phase symbols into data bits in accordance with, e.g., the (1, 10) constraint and a parity state machine that generates parity symbols such that a single inserted parity symbol does not violate the (1, 7) constraint in a run length limited code and furthermore the data following the insertion will not violate the (1, 10) constraint in a run length limited code. The state machines can be used as a trellis to perform maximum likelihood decoding on received coded data, thus performing soft algebraic error detection on received data. The invention thus guarantees better overall error rate performance than hard decision post processing of blocks of detected bits by a parity check matrix which is otherwise vulnerable to loss of bit synchronization at high linear density recording.
摘要翻译：用于代数校正来自磁阻或巨磁阻（MR / GMR）磁头回读波形的复数数字相位信号中的误差的系统和方法包括：数据状态机，其将相位符号编码为数据位，例如，（1,10）约束和产生奇偶校验符号的奇偶校验状态机，使得单个插入的奇偶校验符号不违反游程长度限制代码中的（1,7）约束，此外，插入之后的数据将不会违反（ 1，10）在运行长度限制代码中的约束。状态机可以用作网格，对接收到的编码数据进行最大似然解码，从而对接收到的数据执行软代数误差检测。因此，本发明保证比通过奇偶校验矩阵的硬判决后处理检测到的比特的更好的总体错误率性能，否则在高线性密度记录时易于丢失比特同步。

摘要： An efficient method for finding all the possible corrections of a bust of length b and e random errors consists of finding a polynomial whose roots are the candidate location for l—the location of the beginning of the burst—thus avoiding the search over all possible values of l (it is assumed that the burst is non-trivial, i.e., at least one of its errors has a non-zero value). In order to reduce the number of spurious solutions, it is assumed that the number of syndromes is t=2e+b+s, where s is at least 2. The larger the value of s the less likely it is that the algorithm will generate “spurious” solutions. Once the location of the burst is known, standard procedures are used to determine the magnitudes of the burst errors and the location and magnitude of the random errors.

摘要： An error correction algebraic decoder and an associated method correct a combination of a B-byte burst of errors and t-byte random errors in a failed sector, by iteratively adding and removing an erasure (N−B) times until the entire failed sector has been scanned, provided the following inequality is satisfied: (B+2t)≦(R−1), where N denotes the number of bytes, B denotes the length of the burst of errors, t denotes the total number of random errors, and R denotes the number of check bytes in the failed sector. This results in a corrected sector at a decoding latency that is a generally linear function of the number of the check bytes R, as follows: Decoding Latency=5R(N−B).
