    Abstract: A method and an apparatus of wood pressing usable in manufacturing glued laminated wood such as laminated veneer lumber (LVL) using a number of wood veneer sheets are disclosed. A hot press used for wood pressing includes a pair of heating plates which are disposed one above the other and have pressing surfaces facing each other. The paired heating plates are both movable toward and away from each other. In operation, firstly one of the heating plates is moved toward the other heating plate to a position where the pressing surface of the one heating plate is spaced from a surface to which a veneer sheet is to be glued by a distance corresponding to the thickness of the veneer sheet. Then, the other heating plate is moved toward the one heating plate until a desired pressure is produced pressing.

    Abstract: A rewrite determining unit of a hard disk apparatus acquires a servo signal that includes an offtrack amount corresponding to each servo frame from a position information memory, and determines whether a write fault has occurred based on the servo signal. If a write fault has occurred, the rewrite determining unit determines a rewrite sector count, and a write controller controls a hard disk controller so that rewriting is performed to correspond to the rewrite sector count determined by the rewrite determining unit.

    Abstract: 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.
