摘要:
According to one embodiment, a magnetic storage apparatus configured to write data to and read data from a magnetic medium with a head includes a setting module, a write module, a read module, and a quality measurement module. The setting module sets a plurality of sections divided in the track direction of the magnetic medium and a predetermined reference path along the track direction, and also sets at least one offset for each of the sections such that the offset is different between adjacent sections. The offset is the position of the head with respect to the reference path. The write module writes a first data pattern to the offset set by the setting module and writes a second data pattern to the reference path a predetermined number of times. The read module reads the first data pattern written by the write module. The quality measurement module measures the quality of the first data pattern read by the read module.

One aspect of the embodiments is related to a method of controlling a flying height of a head slider. The method includes the steps of measuring a first correlation value between an air pressure and a heating element sensitivity of the head slider, measuring a second correlation value between the air pressure and the flying height of the head slider, calculating a reference heating-element sensitivity at normal air pressure from the first correlation value, measuring a heating element sensitivity of the heating element when the head slider is lifted, calculating the difference between the heating element sensitivity and the reference heating-element sensitivity to calculate an amount of variation in air pressure from the first correlation value, and calculating an amount of variation in the flying height of the head slider from the amount of variation in air pressure and the second correlation value and controlling the heating element.

An isolated gene encodes for a L-proline-3-hydroxylase having the amino acid sequence of SEQ ID NOS: 1, 2, 15, 16 and 17, or for a protein having enzymatic activity to hydroxylate the 3-position of L-proline and to act on free L-proline in the presence of 2-ketoglutaric acid and divalent iron ions to produce cis-3-hydroxy-L-proline. The gene is inserted into a vector and the resulting recombinant DNA is used to create a transformant. L-proline-3-hydroxylase is produced by culturing the transformant in a medium.

摘要:
An industrially applicable process for producing cis-3-hydroxy-L-proline, which is useful as a raw material for medicines or as an additive to foods. In the process, L-proline is converted into cis-3-hydroxy-L-proline in the presence of an enzyme source which is derived from a microorganism belonging to the genus Streptomyces or Bacillus and which catalyzes hydroxylation of L-proline into cis-3-hydroxy-L-proline, a divalent iron ion and 2-ketoglutaric acid, in an aqueous medium, and the produced cis-3-hydroxy-L-proline is collected from the aqueous medium. A novel enzyme L-proline-3-hydroxylase, a gene of L-proline-3-hydroxylase which is useful for the process, a transformant containing the gene, and a process for producing L-proline-3-hydroxylase using the transformant, is also provided.

According to one embodiment, there is provided a method for determining whether a defect on a disk in an apparatus includes head is a recess or a protrusion. The method detects a first defect on the disk using a read element provided in the head. The method detects a second defect on the disk using a head disk interference sensor provided in the head. The method further determines whether a third defect is a recessed defect or a protruding defect based on a ratio between a first width of the first defect in a radial direction on the disk and a second width of the second defect in the radial direction of the disk. The third defect is identified based on the first defect and the second defect.
