摘要:
While there are contact joining and capacitance type switches for detecting an operation of a door handle, a problem that is to be solved by the invention is to solve problems of contact failure due to aging and a malfunction triggered by rain drops. According to the invention, a piezoelectric sensor (4) has such flexibility as to be annexed to a door handle (3), whereby a minute displacement of the door handle (3) can be detected with high sensitivity. Consequently, a sufficient signal output can be obtained only through a simple touch to the door handle (3), whereby a touch or contact to the door handle (3) can be detected. In addition, since electrodes are not exposed to the outside, the piezoelectric sensor (4) is made difficult to be affected by disturbance, and dust, rain, snow and the like which come to adhere thereto. Furthermore, since the piezoelectric sensor (4) can be deformed with suppleness, there are imposed few limiting conditions on a setting place and a space where to dispose the piezoelectric sensor (4) is diminished.

A control apparatus detects positional information of a head performing writing processing every predetermined time interval, and computes next-sample projected positional information of the head based on the difference between the positional information detected the previous time and the positional information detected the current time, and the current detected positional information for every position information detected. The control apparatus determines whether the computed next-sample projected positional information is greater than a next-sample projected position threshold which is a predetermined threshold. Following this, in the case that determination is made that the next-sample projected positional information is greater than the projected position threshold, the disk control apparatus controls a storage device to stop the writing processing after the writing processing is performed through the end of the sector wherein the writing processing is currently being performed.

A storage device receives and holds a storage medium that is subjected to first servo writing processing for writing servo information, a Gray code of which is offset, from an inner cylinder or an outer cylinder to a predetermined cylinder and, after the first servo writing processing, subjected to second servo writing processing for writing servo information from an opposite direction to the predetermined cylinder and in which Gray codes are written to be offset not to overlap in the first or second servo writing processing and the pieces of servo information having different mark patterns are written in the first servo writing processing and the second servo writing processing. The storage device acquires cylinder information and mark patterns from the servo information written in the held storage medium and controls a position of a head based on the acquired cylinder information and mark patterns.

An amplitude measurement unit measures an amplitude of a read signal from a preamble unit in a servo area of a predetermined frame number m per one rotation of the recording medium for a predetermined cycle number n while increasing an electric power amount distributed to the heater in the state in which the head is positioned to a track on the recording medium, and a mean amplitude calculating unit calculates a mean amplitude from an amplitude measurement value which is measured by the number which is the frame number m multiplied by the cycle number n. A contact determination unit calculates a mean amplitude variation amount per a unit heater electric power amount as a contact determination value, and determines that the head is in contact with the recording medium when the contact determination value is lower than a predetermined threshold value, and a flying height calculating unit which calculates a flying height of the head with respect to the surface of the recording medium from the heater electric power amount at the point when contact is determined.

The present invention is directed to a method of holding a veneer sheet which has been dried to a moisture content lower than the fiber saturation point and also heated to a temperature higher than an ambient temperature of an environment where the veneer sheet is held. The veneer sheet is bent in such way that at least a part of the veneer sheet in the longitudinal section thereof along the grain direction is curved and the same veneer sheet in any transverse section thereof perpendicular to the grain direction is substantially straight. The veneer sheet held bent is held for a predetermined period of time.

Offtrack amounts corresponding to every servo in which data writing has been completed is stored in a storage unit. Offtrack amount corresponding to a next servo frame, which is a servo frame present next to a servo frame for which data has been written, is calculated from the offtrack amounts stored in the storage unit. Based on the offtrack amount of the next servo frame, it is decided whether data needs to be rewritten in a sector present before the next servo frame.
