    摘要: A single-crystal manufacturing apparatus comprises a chamber, a crucible in the chamber, a heater arranged around the crucible, a lifting mechanism for lifting a seed crystal, and a guide passage for the seed crystal and a grown single crystal. In the single-crystal manufacturing apparatus, a material polycrystal contained the crucible is melted by a heater, and the seed crystal is made to contact the molten polycrystal and is lifted. The single-crystal manufacturing apparatus comprises a cylindrical quartz tube having a curved bottom portion, and a dome-shaped quartz plate. The curved bottom portion faces the crucible from the upper portion of the chamber through the guide passage. The quartz plate is arranged to enclose the quartz tube. The quartz tube has a reflecting structure for reflecting a heat ray from at least its bottom portion whereas the quartz plate has a reflecting structure for reflecting the heat ray to the crucible.

    摘要: A seek-information storing unit stores seek information including a correlation between a seek distance indicating a shift distance from a current track to a target track where a target frame for a data input/out is located and a seek time indicating a shifting time that takes for a head to shift from the current track to the target track, based on an actual measurement. A head-shift control unit controls a shift of the head based on an estimated time obtained by adding a rotational delay time that takes until the target frame arrives at the head position after the head arrives at the target track to the seek time acquired from the seek information.

    摘要: A head-slap detecting device detects a head slap. The head slap causes a storage medium to be slapped by at least one storage-medium driving unit that performs at least one of reproduction and recording of data from and to the storage medium. The head-slap detecting device includes a detecting unit that detects the head slap by determining whether a first variable gain obtained from a variable gain amplifier that amplifies an output of data reproduced by the storage-medium driving unit exceeds a predetermined threshold.
