摘要:
A magnetic disk apparatus has a heater for heating a head incorporated in the magnetic disk apparatus, an atmospheric pressure detector for detecting a change in atmospheric pressure in the magnetic disk apparatus, and an adjuster for adjusting a thermal dose supplied to the head by the heater according to the change in atmospheric pressure detected by the atmospheric pressure detector.

In a storage medium to which information is recorded by using a write head of an inductive type, in addition to a servo section in which servo information is recorded and a data section to which data is to be written, a write training section on which training write of pseudo-data is to be performed is disposed on a recording track. When the temperature is low, a write control unit writes the pseudo-data to the write training area and then writes data to the data area. By writing the pseudo-data to the write training area, a write core is heated and caused to project toward the medium surface side by thermal expansion, and the writing ability is enhanced; then, the data is written to the data section. A write training section is also disposed in front of a data section in a track of a system area of the storage medium, and, when the temperature is low, and when system information is to be written to the data section of the system area, pseudo-data is written to the write training section.

Upon correction, a preheat sector number measurement unit measures a preheat sector number which corresponds to transition time from when electric power distribution to and heating of the heater by preheat electric power is started until when it is stabilized to a predetermined target flying height. Upon reproduction or recording, a flying height control unit distributes electric power to the heater from a sector position which is before a target sector by the preheat sector number so as to perform preliminary heating, and then controls the flying height of the head to a predetermined target flying height from a target sector position.

In a magnetic disk unit, a number of heads that is settable to a usable setting is less than a maximum number of heads providable in the magnetic disk unit. The magnetic disk unit includes a storage part to provide a buffer region that is usable as a data buffer, a reading part to read head information from a magnetic disk, and a control part to reserve a storage region in the storage part for storing the head information based on the maximum number of heads included in the head information. The control part also stores parameters with respect to the heads having the usable setting in reserved storage region, and releases a region of the storage part other than a storage region occupied by the parameters of the reserved storage region, when storing the head information in the storage part.

A write head, which is positioned by reading a servo pattern with a read head, writes data on even tracks of a magnetic disc, and then writes data on odd tracks. Then a read head is positioned on a read position and sequentially reads all the written data. As a result, it is decided whether a read error has occurred. Further, positional deviation of the tracks, in which the read error occurs, is measured.

There is provided a single panel type video display capable of increasing the luminance of image. A color separator separates light from a light source into light beams in three colors in a band shape to emit the light beams and introduces the band-shaped light beams in the three colors so as to be overlapped with one another in a predetermined region. A lens array wheel has a plurality of functional units each composed of a convex lens of a size corresponding to the predetermined region, circularly passes the plurality of functional units each composed of the convex lens through the predetermined region, and scrolls the band-shaped light beams in the three colors in a state where they are divided among regions on a single liquid crystal display panel. A video signal is fed to the liquid crystal display panel in synchronization with the movement of the plurality of functional units each composed of the convex lens.

A method for placing an insertion point in an electronic document in an electronic system for creating and editing an electronic document. Context information regarding a location of a cursor in the electronic document is collected. A coinciding rule is selected from one of a number of rules based on the collected context information. In response to selecting a coinciding rule, the cursor is changed to indicate an anticipated location of the insertion point and the associated formatting rules to be applied. A determination is made whether an indication has been received to place the insertion point in the electronic document, and, if so, then formatting is performed to place the insertion point in the electronic document.

There is provided a highly reliable screen input type display device using a touch panel which can facilitate the control of a gap formed between upper and lower substrates and can stabilize the linearity of the resistance value detection of a resistance film, whereby an erroneous detection of coordinated can be eliminated. For this purpose, a tape-like conductive pressure sensitive adhesive member, which is formed by sandwiching a metal foil with conductive pressure sensitive adhesive material, is used at a connection portion between an upper wiring electrode mounted on an upper resistance film formed on an upper substrate and an inter-substrate connection wiring electrode formed on a lower substrate.
