摘要： PROBLEM TO BE SOLVED: To provide a method of determining an error value, concerning a long burst error correction, also known as an erasure correction, and a lost data correction.
SOLUTION: The method of determining an error value includes: a step of loading an error correction code (ECC) entity having a line indicating a data symbol; a step of determining an error position with respect to a first line; a step of generating an error syndrome with respect to the first line; a step of determining an erasure constant from the error position; a step of determining the error position with respect to each of the rest of lines; a step of generating the error syndrome with respect to each of the rest of lines; and a step of determining the error value with respect to each line from the corresponding error position and the corresponding error syndrome and the constant.

摘要： PROBLEM TO BE SOLVED: To provide a fastening system (26) for a memory system (10), for fastening a memory device (24) to a housing assembly (52). SOLUTION: The fastening system (26) includes a first fastener unit (450) having a fastener (506) and a release assembly (456). At a latched position (500), the fastener (506) secures the memory device (24) to a housing assembly (52). Alternatively, at an unlatched position (502), the memory device (24) can be removed from the housing assembly (52) by the fastener (506). The release assembly (456) moves the fastener (506) between the latched position (500) and the unlatched position (502). COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method, apparatus and system for facilitating recording of servo signals on a recording medium such as a magnetic tape with high accuracy.
SOLUTION: Variation of inter-frame and intra-frame placement is substantially reduced by writing successive frames or sub-frames based on a detection of a previously-written frame or sub-frame by a read element. Appropriate placement of the read element in relation to servo write elements, on a multi-gap servo write head, ensures the correct placement of successive frames on the recording medium.

摘要： PROBLEM TO BE SOLVED: To provide a method, equipment, and a system directed to run-lengthlimited (RLL) encoding of data.
SOLUTION: In an embodiment, concatenatable RLL codes with run lengths of zero not exceeding (k) are constructed for any rate N(N+1). As code rates increase, the value of (k) departs from the minimum possible value more slowly than that of many other codes. Further, occurrences of k-bit run lengths occur only at the juncture of two codewords. Due to this property, the codes become ideal for parity bit insertion application such as LDPC channels. In one implementation, the bit address of violating sequences in a table is arranged at the beginning of the codeword, and the user data occupying the locations where the table entries are placed are moved into the locations of the violating sequences. This is done repeatedly, and this is done in a way which provides for cases that the violating sequence is inside the address table itself.

摘要翻译：要解决的问题：提供一种方法，设备和针对数据的长度限制（RLL）编码的系统。解决方案：在一个实施例中，对于任何速率N（N + 1）构建游程长度为零不超过（k）的可连接的RLL码。随着码率的增加，（k）的值比许多其他码更慢的最小可能值。此外，k位运行长度的出现仅在两个码字的接合处发生。由于该特性，代码成为诸如LDPC信道之类的奇偶校验位插入应用的理想选择。在一个实现中，表中的违规序列的位地址被排列在码字的开始处，并且占据表条目所在位置的用户数据被移动到违规序列的位置。这是重复完成的，这是通过一种方式来完成的，这种方式可以提供违反序列在地址表本身内的情况。版权所有（C）2008，JPO＆INPIT
