摘要： In recording and/or reproducing data into and from a disk record medium having a record medium in which a plurality of tracks are arranged radially, the record area is divided into a plurality of zones, and a clock frequency is assigned to each zone. The data recording and/or reproducing are performed according to the clock of the frequency assigned to the respective zone. Each zone is subdivided to include a plurality of tracks, and a clock having a different frequency is assigned to each zone. Each frequency is set in such a manner that the record capacity of the track gradually becomes larger as the zone is nearer to the outer zone.

摘要： In a method for recording/reproducing information, a reference pattern is recorded in a certain predetermined domain so that the leading-edge and the tailing-edge of a certain recorded portion are positioned in a predetermined relationship, when coded bits of data are recorded on a recording medium by forming recorded portions physically different from not recorded portions, while making them correspond to leading-edges and tailing-edges of the recorded portions. A first and a second reproduced signal indicating the leading-edge and the tailing-edge of the recorded portion, respectively, are detected independently from each other from a reproduced waveform corresponding to the recorded portion, which has been thus recorded; and the first and the second reproduced signal are reconstructed while correcting edge shifts produced at recording data by storing the first and second reproduced signal in a memory, so that the first and the second reproduced signal indicate the leading-edge and the tailing-edge of the recorded portion corresponding to the reference pattern, respectively, in the predetermined relationship.

摘要： A coating is applied on an optical fiber drawn from a melted tip of an optical-fiber preform. A glass spin is applied to a coated optical fiber by gripping the coated optical fiber with at least a pair of spinning applying rollers arranged in different levels with parallel rotation axes, rotating the spinning applying rollers so that the coated optical fiber is guided in a predetermined direction, and alternately shifting the spinning applying rollers in opposite directions along the rotation axes. The glass spin is applied to the coated optical fiber in a state in which each of the rotation axes is tilted at a predetermined angle from a plane perpendicular to the first direction.

摘要： A circuit for detecting the variation of resistance of a variable-resistance element comprises a pair of grounded-base transistors with their base electrodes provided with different base voltages and with their emitter electrodes connected to both terminals of the variable-resistance element so that the voltage between both terminals of the element is kept constant. The current density of the variable-resistance element does not vary when the resistance of the variable-resistance element varies, whereby the lifetime of the element can be prolonged.
