摘要： An image forming apparatus that previously rotates a polygonal mirror drive motor before starting a job and forms a latent image by using an optical scanning unit including the polygonal mirror drive motor is provided. The image forming apparatus includes a control unit configured to perform control such that, in the determination of the presence or absence of each of color toners before a previous rotation is started, if it is determined that any one of the color toners is absent, only the polygonal mirror drive motor corresponding to a black toner is previously rotated.

摘要： Embodiments of the invention improve utility of a magnetic disk drive in which a head is retracted if the magnetic disk drive is in a dropping state. In one embodiment, an HDC/MPU provided in a magnetic disk drive judges whether the magnetic disk drive is in a dropping state based on an output from an acceleration sensor which may detect an acceleration and performs a retraction operation of a head. After the HDC/MPU judges that a drop is occurring, the HDC/MPU detects whether the drop judgment is incorrect according to whether a shock sensor detects a shock occurrence and changes the drop judgment condition based on a detection history of detected incorrect judgments.

摘要： Embodiments of the invention provide ways to write data in a load/unload area. In one embodiment, address numbers (ranging from 981 to 1065) whose order of addressing by host equipment is later than that of address numbers (ranging from 1 to 980) as logical block addresses (LBAs) assigned to data sectors in the data area are assigned as LBAs to data sectors whose absolute block addresses (ABAs) range from 1001 to 1100 in the load/unload area. As a result, when the host equipment performs addressing in a magnetic disk drive, the priority order given to the load/unload area becomes low. Accordingly, with the storage capacity being increased, it is possible to prevent the substantial performance from decreasing.
摘要翻译：本发明的实施例提供了在加载/卸载区域中写入数据的方式。在一个实施例中，作为分配给数据区域中的数据扇区的逻辑块地址（LBA），其主机设备的寻址顺序晚于地址号（范围从1到980）的地址号（范围从981到1065）是被分配为LBA到其加载/卸载区域的绝对块地址（ABAs）的范围从1001到1100的数据扇区。结果，当主机设备在磁盘驱动器中执行寻址时，给予加载/卸载区域的优先顺序变低。因此，随着存储容量的增加，可以防止实质性的降低。

摘要： A belt feeding apparatus includes an endless belt and a supporting member for rotatably supporting the belt. The belt feeding apparatus further includes a setting member for setting, when the belt is deviated from a widthwisely normal zone, an inclination angle of the supporting member to a return angle to return the belt toward the normal zone. The setting member also sets, when a predetermined time elapses from the belt returning to the normal zone, the inclination angle of the supporting member to a balance angle to keep the belt in the zone.

摘要： Embodiments of the present invention relate to retracting a magnetic head of a disk drive device to a retract position in accordance with a fall state, and to suppressing the performance degradation due to erroneous fall determinations as well as occurrence of damage by a head-disk crash. According to one embodiment of the present invention, in a Hard Disk Drive (HDD), a servo controller moves a head slider to a cylinder at the side of a ramp at a predetermined timing that a fall determiner determines that it is falling and an unload controller starts an unload process. This shortens the time between determination by the fall determiner that it is falling to retraction of the head slider to the retract position. Furthermore, it prevents increase of the erroneous determinations by relaxing the fall determination condition for safety. Also, it shortens the time that the head slider returns to the initial position before the seek in case that it is not determined that it is falling.
摘要翻译：本发明的实施例涉及根据跌倒状态将盘驱动装置的磁头回缩到缩回位置，并且抑制由于错误的下降判定引起的性能下降以及头盘崩溃的损坏的发生。根据本发明的一个实施例，在硬盘驱动器（HDD）中，伺服控制器在预定定时将磁头滑块移动到斜坡侧的气缸，以便下降确定器确定其正在下降并且卸载控制器启动卸载过程。这缩短了下降确定器确定其下降到头部滑块缩回到缩回位置之间的时间。此外，通过放松用于安全的跌倒判定条件，防止了错误判定的增加。而且，如果没有确定它正在下降，它会缩短磁头滑块在搜索之前返回到初始位置的时间。

摘要： A magnetic circuit is provided in an enclosure that can efficiently generate magnetic flux from the enclosure, configuring a magnetic disk, to a magnetic disk. Thus, by providing such a magnetic circuit, a magnetic field different from that in other enclosure parts, that is, a local magnetic field, is generated from the magnetic circuit in case the disk device is set in an external magnetic field. Hence, this local magnetic field can effectively erase data in the magnetic disk. In particular, since the local magnetic field is generated even if the external magnetic field is weak, it is possible to not only suppress the demagnetization of permanent magnets used in the spindle motor at minimum, but also effectively erase data in the magnetic disk.
摘要翻译：在外壳中提供磁路，其可以有效地从壳体产生磁通量，将磁盘配置到磁盘。因此，通过设置这样的磁路，在将磁盘装置设定在外部磁场的情况下，从磁路产生与其它外壳部分不同的磁场，即磁场。因此，该局部磁场可以有效地擦除磁盘中的数据。具体地说，由于即使外部磁场较弱也产生局部磁场，所以不仅可以抑制主轴电动机中使用的永久磁铁的退磁至少，还可以有效地擦除磁盘中的数据。
