Methods, logic, apparatus and computer program product write data, comprising less than a full Data Set, to magnetic tape. Data is received from a host, a do-not-interleave command is issued and C1 and C2 ECC are computed. Codeword Quad (CQ) sets are then formed. At least one CQ set of the Data Set is written to a magnetic tape in a non-interleaved manner and a Data Set Information Table (DSIT) is written to the magnetic tape immediately following the at least one written CQ set. An address transformation may be used to cancel interleaving. Writing a CQ set may include writing a plurality of contiguous instances of the CQ set to the magnetic tape to maintain the effectiveness of ECC capability.

During a read-after-write operation on magnetic tape, a first SCO is formed which includes two encoded processed user data units and is one of T SCOs in a first SCO set. The user data units are each one of T user data units in first and second user data unit sets, respectively, within the first SCO set. The first SCO set is written to the magnetic tape and is immediately read. When an error is detected in one of the user data units, a second SCO is formed to include the first user data unit and, only if an error is not detected in a user data unit in the other user data unit set, to not include the other user data unit, the second SCO being one of T SCOs in a second SCO set. Then, the second SCO set is rewritten to a later position on the tape later.

It identifies the on-substrate arrangement position information of the transfer products which are fabricated on the same substrate without increasing the fabrication processes.The process of repeatedly exposing a plurality of transfer product patterns which are depicted on a sheet of photo mask are repeatedly exposed on a substrate S times, and in at least two exposure processes among the S times exposure processes, photo masks on which different identification patterns are depicted for each of the plural transfer product patterns are employed to carry out the exposure processes repeatedly, and the number of transfer product patterns which are transferred at one time are differentiated between a process in the at least two exposure processes and the other processes.

Method and apparatus are provided for encoding and decoding rate-(s(K+1)/s(K+1)+1) TCMTR(j,k,t,a) codes, where s is the ECC symbol size in bits and K is the number of unencoded symbols that are interleaved with an (s+1)-bit encoded block at the output of a rate-s/(s+1) encoder that encodes the r-th s-bit symbol. K=m/s−1 where m=s(K+1) is the total number of bits to be encoded. Error propagation is reduced, thus allowing the ECC code to correct errors efficiently. Header error-rate is also reduced by eliminating occurrence of likely error events at the detector output. Although initially an RLL code may be designed for an ECC symbol size of s bits, the RLL encoding of the present invention may be used in conjunction with ECC schemes that utilize symbol sizes other than s bits.

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.

A manufacturing method of a solid-state imaging device prevents generation of a space due to insufficient filling of a conductive material. Materials constituting a multilayer film 41 are sequentially deposited on a semiconductor substrate, and portions respectively included in a plug formation intended region and a surrounding region that surrounds the plug formation intended region are removed from the deposited multilayer film 41. Next, the plug formation intended region and the surrounding region from which the portions have been removed is refilled with a single insulating material, and a hole is formed on the plug formation intended region by etching. Then, the formed hole is filled with a conductive material to therefore form a plug.

Style sheets indicating layouts of a plurality of types are stored in a server. The user of a client computer selects the style sheet having the desired layout. When the user of the client computer subsequently accesses the server for the purpose of conducting a search, the results of the search are displayed on the selected style sheet. The user need not select the desired style sheet whenever the server is accessed.

A woodwind instrument has a key mechanism for selectively closing and opening tone hole chimneys formed on a tube, and the key mechanism includes keys supported by a linkage at the associated tone hole chimneys; each of the keys includes a retainer inserted between a pad cup and a pad, and the retainer has a backing plate portion held in area contact with at the inner surface thereof to the pad and in point contact with at the outer surface thereof to the pad cup so that an assembling worker adjusts the pad to an appropriate attitude in the pad cup by pressing the pad to the associated tone hole chimney, and, thereafter, secures the retainer to the pad cup; this results in that the player can seal the tone hole chimney with the pad through a simple adjusting work.

Original images, large images, medium images and thumbnail images are registered with a server system. An original-image file is transmitted from a client computer to the server system. The server system converts the format of the original-image file to generate a large-image file, generates a medium-image file, in which the quantity of data is less than that of the large-image file, from the large-image file, and generates a thumbnail-image file, in which the quantity of data is less than that of the medium-image file, from the medium-image file. The original-image file, large-image file, medium-image file and thumbnail-image file are placed on one folder and stored in an image file unit. After the folder containing the original-image file, etc., has been stored in the image file unit, the user of a client computer having access privileges is capable of accessing files such as the large-image file.
