    摘要： A head is moved in a lateral direction on the boundary between a separation track and a recording track on a recording medium. The separation track isolates the adjacent recording tracks from each other. A variation is detected in the output supplied from the head based on the recording track. Positional information indicating the position of the head is generated based on the variation. The output supplied from the head varies in response to the movement in the lateral direction, namely the elapsed time. The positional information can thus be generated based on the variation in the output. The generated positional information contributes to an accurate positioning in a facilitated manner. Moreover, information required to position the head can be omitted from the recording medium. The processes can be simplified in the production of the recording medium. The operation time can thus be shortened.

    摘要： A method for producing a 1,2,4-oxadiazol derivative represented by the formula (1): (1) [wherein, R1 represents a methyl group or a phenyl group, and R2 represents an optionally substituted linear or branched alkyl group], which comprises reacting a nitrile represented by the formula (2): (2) [wherein, R2 represents an optionally substituted linear or branched alkyl group] with acetone or acetophenone in the presence of iron (III) nitrate. The method allows a 1,2,4-oxadiazol derivative exhibiting a useful biological activity to be produced in good yield without the discharge of a harmful waste.

    摘要： A method for overwriting information in a magneto-optical memory medium which includes a simultaneous writing and erasing step of continuously irradiating a written information-carrying area of the recording layer of the memory medium with two different pulses from a single laser beam head in accordance with information to be written, regardless of the presence or absence of written information. A variation includes irradiating the written information-carrying area with an erasing pulse from a laser beam head, regardless of the presence or absence of written information, and then selectively irradiating the information-erased area with a writing pulse from another laser beam head in accordance with information to be written. According to these methods, it becomes possible to carry out a simple and high-speed overwriting with an increased and stabilized bit positioning accuracy.

    摘要： A nanohole structure includes a metallic matrix and nanoholes arrayed regularly in the metallic matrix, in which the nanoholes are spaced in rows at specific intervals to constitute rows of nanoholes. The rows of nanoholes are preferably arranged concentrically or helically. The nanoholes in adjacent rows of nanoholes are preferably arranged in a radial direction. The width of each row of nanoholes preferably varies at specific intervals in its longitudinal direction. A magnetic recording medium includes a substrate, and a porous layer on or above the substrate. The porous layer contains nanoholes each extending in a direction substantially perpendicular to a substrate plane, containing at least one magnetic material therein, and is the above-mentioned nanohole structure.
