The present invention relates to a method for obtaining an antibody from an avian B cell antibody library, comprising the following steps (a) to (d):

Method for obtaining antibody

According to one embodiment, a drive array apparatus includes a plurality of data storage drives constituting a drive array and a controller. The controller divides all data storage areas of each of the data storage drives into a plurality of logical unit areas and associates and manages each of the logical unit areas and each of the data storage drives. The controller identifies a logical unit area of an error occurrence object based on a notification from a data storage drive where an error occurred, restores data of the identified logical unit area, and performs reconfiguration processing of the drive array.

A read head of a head device used in a disk storage apparatus is provided including a spin-valve magnetoresistive (MR) element. The spin-valve MR element comprises a pinning magnetic layer of which magnetizing direction is determined, a free magnetic layer of which magnetizing direction can be shifted by a signal magnetic field derived from the disk, and a non-magnetic layer sandwiched between the pinning magnetic layer and the free magnetic layer. The head also includes a remagnetization layer which functions as a control element for correcting the magnetizing direction of the pinning magnetic layer.

Head device having spin-valve read head for use in a disk storage

A data storage system that uses a magnetic head assembly having a write head and a read head mounted on a slider to write on and read from a disk. A portion of the coil of the write head is used as a wear sensor for detecting wear on the surface of the slider. A head IC monitors the coil voltage and, when it goes lower than a reference voltage, detects the occurrence of a fault in the write head due to excessive wear on the slider surface. In response to the detection of the fault in the write head by the head IC, a control driver prohibits a write operation and saves data already recorded on the disk.

Apparatus for detecting error in magnetic head for use in disk storage

A magnetic disk drive, which controls the seek and positioning of a magnetic head for recording and reproducing data to a specific position on the magnetic disk in accordance with the servo data recorded in the magnetic disk, comprises measuring means for measuring one of an atmospheric pressure and a height above sea level and head positioning control means for setting a seek speed in accordance with the measured values measuring by said measuring means, and for controlling the seek and positioning of the magnetic head to the specific position on the disk at the set seek speed.

Magnetic disk drive where seek speed depends on atmospheric pressure and

The dimension ratio t/H of the thickness t of a flexure spring to the height (thickness) H of a slider 17 is set at 0.047 or less in order to reduce the variation in crown amount due to a temperature variation. As the ratio of the thickness t of the flexure spring to the height H of the slider decreases, the stress acting in the slider due to a difference in linear expansion coefficient between itself and the flexure spring decreases and the rigidity of the slider increases relative to the flexure spring. The dimension ratio H/L of the height H of the slider to the length L thereof is set at 0.245 or more. As the dimension ratio H/L increases, the rigidity of the slider increases and the amount of deformation of the slider due to a difference in linear expansion coefficient between itself and the flexure spring decreases. In addition, the ratio A2/A1 of an actual adhesion area A2 between the slider and a slider fixing portion of the flexure spring to a possible adhesion area A1 therebetween is reduced to 0.42 or less. Moreover, a temperature compensation member is adhered to the slider or the flexure spring.
