Abstract: Exposure position marks are reliably recognized and the displacement of an exposure position is correctly and efficiently detected based on measurement results produced by recognizing the marks. The exposure position marks are constructed of a first pattern made up of an inner quadrangular pattern and an outer quadrangular pattern and a second pattern shaped as a rectangular frame whose inner edge and outer edge are formed as quadrangular patterns. The first pattern and the second pattern are formed with an intention of making center positions of the first pattern and the second pattern match and of having the second pattern disposed inside a region between an inner quadrangular pattern and an outer quadrangular pattern of the first pattern. The displacement of the exposure position is found by calculating an average of a measurement produced by detecting a displacement between the center positions of the inner quadrangular pattern of the first pattern and the quadrangular pattern that is the inner edge of the second pattern and a measurement produced by detecting a displacement between the center positions of the outer quadrangular pattern of the first pattern and the quadrangular pattern that is the outer edge of the second pattern

Abstract: A thin film magnetic head having a high write-in accuracy can be produced by suppressing a magnetic field leak between upper and lower magnetic poles. The method of producing the thin film magnetic head, in which a head substrate, magnetoresistance effect element, lower magnetic pole, write gap layer and an upper magnetic pole are formed in this order, has the lower magnetic pole patterned with a larger width than that of the upper magnetic pole in a write magnetic pole after the lower magnetic pole is formed. An insulation layer is formed in the same layer as the lower magnetic pole such that the insulation layer is flattened with the lower magnetic pole. The upper magnetic pole is formed on a surface of the write gap layer after the write gap layer is formed, and a protrusion of the lower magnetic pole is removed from a side face thereof.

Abstract: The thin film magnetic head having a high write-in accuracy can be easily produced by suppressing a magnetic field leak between an upper magnetic pole and a lower magnetic pole. The method of producing the thin film magnetic head, in which a head substrate, a magnetoresistance effect element (14), a lower magnetic pole (20), a write gap layer (24) and an upper magnetic pole (26) are formed in this order, is characterized in that the lower magnetic pole (20) is so patterned as to have a larger width than the width of the upper magnetic pole (26) in a write magnetic pole after the lower magnetic pole is formed, that subsequently an insulation layer (30) composed of a non-magnetic material is formed in the same layer as the lower magnetic pole (20) in such a manner that the insulation layer (30) is flattened together with the lower magnetic pole, that the upper magnetic pole (26) is formed on a surface of the write gap layer (24) after the write gap layer (24) is formed on surfaces of the lower magnetic pole (20) and the insulation layer (30), and that finally a protrusion of the lower magnetic pole is removed from a side face thereof by FIB trimming.

Abstract: A method for linking data for recording on a recordable type of optical disk with data encoded according to a specific encoding using a CIRC type error correction system. The pieces of data are organized in frames, in blocks of p frames and in groups of n blocks. The frames of data and frames of sub-codes are synchronized by using pieces of information pre-recorded on the disk. During encoding, each group of n blocks receives and is preceded by three redundant blocks, namely a run-in block (RIN) itself preceded by a first dummy block (DMI) and second dummy block (DM2); and is follwed by two redundant blocks, namely a run-out block (ROUT) which is followed by a third dummy block (DM3). During writing on the disk, the length of the three redundant blocks is sufficient. They effectively set-up the record and reading of the data and its interleaving and error correction code. The disclosed method can be applied particularly to recordable optical compact disks.
