Abstract: A method for randomizing data to mitigate false VFO detection is described. In one embodiment, such a method includes simultaneously receiving multiple input data streams. Each input data stream is associated with a different track on a magnetic tape medium. The input data streams are simultaneously scrambled to produce multiple randomized data streams. The input data streams are scrambled such that different bit patterns are produced in the randomized data streams even where corresponding bit patterns in the input data streams are identical. The randomized data streams are simultaneously written to their associated data tracks on the magnetic tape medium.

Abstract: A target space ratio of a monitor pattern on a substrate for inspection is determined to be different from a ratio of 1:1. A range of space ratios in a library is determined to include the target space ratio and not include a space ratio of 1:1. The monitor pattern is formed on a film to be processed by performing predetermined processes on the substrate for inspection. Sizes of the monitor pattern are measured. The sizes of the monitor pattern are converted into sizes of a pattern of the film to be processed having a space ratio of 1:1, and processing conditions of the predetermined processes are compensated for based on the sizes of the converted pattern of the film to be processed. After that, the predetermined processes are performed on a wafer under the compensated conditions to form a pattern having a space ratio of 1:1 on the film to be processed.

Abstract: A device, method, and program are provided to prevent an increase of the probability of erroneous correction for a burst error having a length exceeding detection capability even if high correction capability is selected for a random error. In one embodiment, an apparatus corrects errors in a product code block including C1 codes in a row direction and C2 codes in a column direction. First, a C1 decoder performs C1 correction for each of an even C1 including even-numbered bytes in the C1 code and an odd C1 including odd-numbered bytes in the C1 code. Next, a C2 decoder performs erasure correction in C2 correction in the case where any one of the C1 correction results for the even C1 and the odd C1 is correction failure, and where one of the results is the 3-byte correction while the other one is the correction failure or the 3-byte correction.

Abstract: An apparatus and method for reading out data recoded on a tape with a read head is provided. A command processing unit receives a request for reading out old data behind EOD of new data. A channel input/output unit receives, data read out with a read head and a buffer managing unit receives this data.

Abstract: Conventional C2 coding and interleaving for multi-track data tape in LTO-¾ do not support recording data onto a number of concurrent tracks which is not a power of two. Higher-rate longer C2 codes, which do not degrade error rate performance, are provided. An adjustable format and interleaving scheme accommodates future tape drives in which the number of concurrent tracks is not necessarily a power of two. A data set is segmented into a plurality of unencoded subdata sets and parity bytes are generated for each row and column. The parameters of the C2 code include N2 as the least common multiple of the number of possible tracks to which codeword objects are to be written. COs are formed from N2 C1 codewords, mapped onto a logical data track according to information within headers of the CO and modulation encoded into synchronized COs which are written to the tape.

Abstract: For writing data to multi-track tape, a received data set is received and segmented into unencoded subdata sets, each comprising an array having K2 rows and K1 columns. For each unencoded subdata set, N1−K1 C1-parity bytes are generated for each row and N2−K2 C2-parity bytes are generated for each column. The C1 and C2 parity bytes are appended to the ends of the row and column, respectively, to form encoded C1 and C2 codewords, respectively. All of the C1 codewords per data set are endowed with a specific codeword header to form a plurality of partial codeword objects (PCOs). Each PCO is mapped onto a logical data track according to information within the header. On each logical data track, adjacent PCOs are merged to form COs which are modulation encoded and mapped into synchronized COs. Then T synchronized COs are written simultaneously to the data tape where T is the number of concurrent active tracks on the data tape.

Abstract translation: 为了将数据写入多轨磁带，接收到的数据集并被分割成未编码的子数据集，每个子​​集包括具有K2行和K1列的阵列。 对于每个未编码的子数据集，为每行生成N1-K1 C1-奇偶校验字节，并为每列生成N2-K2 C2-奇偶校验字节。 C1和C2奇偶校验字节分别附加到行和列的末端，分别形成编码的C1和C2码字。 每个数据集的所有C1码字都具有特定的码字头以形成多个部分码字对象（PCO）。 每个PCO根据标题内的信息被映射到逻辑数据轨道上。 在每个逻辑数据轨道上，相邻的PCO被合并以形成被调制编码并被映射到同步的CO中的CO。 然后将T同步的CO同时写入数据磁带，其中T是数据磁带上的并发活动磁道的数量。
