    摘要: An optical disk device for writing data into a disk including a plurality of recording layers, wherein the disk includes a recording layer in which a track for recording the data is formed in a clockwise spiral direction, and a recording layer in which a track for recording the data is formed in a counter-clockwise spiral direction, and the optical disk device records the data into a first recording layer, and selects a layer in which the data can be recorded and of which a spiral direction is opposite to the spiral direction of the first recording layer, as a recording layer for recording the data next to the first recording layer.

    摘要: A sheet feeding device includes a sheet loader, a sheet feeder, a misfeeding detector, a memory, and circuitry. The sheet loader is configured to load a sheet of a sheet bundle. The sheet feeder is configured to feed a sheet from the sheet bundle loaded on the sheet loader. The misfeeding detector is configured to detect a misfeeding of the sheet. The memory is configured to store sheet feed information on sheet feeding. The circuitry is configured to change a sheet feed setting based on the sheet feed information stored in the memory and perform a retry sheet feeding at a detection of the misfeeding by the misfeeding detector.

    摘要: When a laser light focal point, driven by an objective lens, passes through each of a plurality of recording layers of an optical disc, data recorded on the recording layers through which the focal point passes may be deteriorated due to a difference in optical sensitivity for each recording layer or the like. In a focal point position movement in which switching of recording layers is made by a focus error signal, when the focal point position moves from a recording layer on which a laser light is focused to another recording layer which is not adjacent, light intensity or light density at the focal point is reduced in accordance with the recording layer to be passed through, thus deterioration of the data on the optical disc being prevented.
