    摘要: There are provided a storage apparatus and a computer-readable recording medium, on whose storage areas, servo frames are arranged at uniform intervals in a spoke-like pattern. Each of the servo frames has an index bit storing section storing, as an index bit, part of an index pattern, which is operable to identify a storage area. The apparatus and the recording medium have a storage area recognizing unit for recognizing the storage areas based on the index bits, which are obtained by an index bit obtaining unit. The index bits, stored one in each of the index bit storing sections of the servo frames, are adapted to form, when being sequentially arranged, an index bit string in which such an index pattern repeatedly appears.

    摘要: A recording apparatus capable of securely reading out data for causing a head to follow along circular tracks set virtually. Therefore, on-track control along the virtual tracks is possible by the conversion data on the discoid record medium even when, for example, the printed circuit board in a recording apparatus has been replaced.

    摘要: A magnetic disk incorporated into a magnetic disk device is divided radially into a plurality of areas. An inner-circumference area has servo information written thereon at a low frequency. An outer-circumference area has servo information written thereon at a high frequency. The magnetic disk device creates concentric tracks on the magnetic disk with a magnetic disk rotation center as the center of the concentric tracks and selects a dividing track that acts as a demarcation for switching the area from which servo information will be read. The magnetic disk device then deletes all the servo information that is not going to be read in each of the areas divided by the dividing track.

    摘要: A disk device performs position control of a head. An acquiring unit acquires correction information and check information from a disk for checking the correction information. A judging unit judges whether the correction information acquired should be used for correcting position information recorded in the disk, based on the correction information acquired and the check information acquired.

    摘要: An α-trifluoromethyl-α,β-unsaturated ester can be produced by reacting an α-trifluoromethyl-α-hydroxy ester with sulfuryl fluoride (SO2F2) in the presence of an organic base. It is preferable that the raw substrate has a hydrogen atom as one β-position substituent group and either an alkyl group, a substituted alkyl group, an alkenyl group, a substituted alkenyl group, an aromatic ring group or a substituted aromatic ring group as the other β-position substituent group. It is more preferable that an ester moiety of the raw substrate is an alkyl ester. This raw substrate is readily available. Further, the desired reaction can proceed favorably with the use of this raw substrate. It is also preferable to use either 1,5-diazabicyclo[4.3.0]non-5-ene (DBN) or 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) as the organic base. The desired reaction can proceed more favorably with the use of this organic base.
