摘要:
Amplitude and frequency of a high-frequency signal superposed on a reproduction laser beam are changed in accordance with a reproduction spot diameter on the surface of the recording layer upon discrimination of an optical disk in initial adjustment after insertion of the optical disk and change of a layer of a multi-layer optical disk. Further, the high-frequency signal is not superposed on the reproduction laser beam until end of the discrimination and change to a target layer upon discrimination of the optical disk and change of a layer of a multi-layer optical disk.

According to one embodiment, an information processor, which is capable of supplying power to an external device, includes a connector, a storage module, and a power supply control module. The connector connects the external device to the information processor. The storage module stores a plurality of power supply modes each defining conditions of respective modules of the information processor to make the external device connected to the connector chargeable. The power supply control module selects a power supply mode effective for the external device from the power supply modes when the external device is connected to the connector, and sets the respective modules of the information processor according to the conditions corresponding to the power supply mode selected.

An optical pickup includes a diffraction grating partitioned into three areas, in which the phase of periodic grating groove structure in an area is successively shifted from that in the adjacent area by 90°. In the generation of a differential push-pull signal, an amplification factor K for sub push-pull signals is varied depending on the type of the optical disk. By such composition of the optical pickup, amplitude deterioration of the tracking error signal accompanying displacement of the object lens is reduced.

When an image forming apparatus is disabled due to a cause rather than the detection of the toner empty condition, it is determined whether a recovery operation is a first recovery operation or a second recovery operation. The first recovery operation is associated with a mounting/dismounting of the toner cartridge performed from when the image forming apparatus is disabled until when the recovery operation begins. The second recovery operation is not associated with the mounting/dismounting. A toner supply control controls the toner supply operation when the recovery operation is performed on condition that the empty memory memorizes that the toner empty detector detects the empty condition. When the recovery operation is the first recovery operation, the toner supply control allows the toner to be supplied into the developer housing. While, when the recovery operation is the second recovery operation, the toner supply control prohibits the toner from being supplied into developer housing.

An information processing apparatus includes: a non-volatile memory that stores a BIOS program that performs legacy emulation process for enabling a device not supported by an operating system to be accessed from the operating system; a controller that controls the device; a boot process unit that performs a boot sequence for booting the operating system stored in the device by controlling the controller through the legacy emulation process of the BIOS program; and a legacy emulation process control unit that performs a stop control process including: monitoring write access by software to a predetermined register, in which a value for designating an operation environment for controlling the device to the controller is set; and aborting execution of the legacy emulation process by the BIOS program when the write access is detected.
