摘要： Embodiments in accordance with the present invention suppress an adverse influence on a pattern of a magnetic disk due to its rotational jitter and write the pattern at more accurate timing. In accordance with one embodiment, a hard disk controller/microprocessing unit (HDC/MPU) controls a clock frequency of a data clock generation circuit so that a rotational jitter of the magnetic disk be compensated when writing and reading user data. The HDC/MPU expects a detection timing of next adjacent servo sector using an error between an actual detection timing and an expected detection timing of a servo sector which has already been detected. The HDC/MPU controls the clock frequency using the expected timing and writes and reads user data between current servo sector and next adjacent servo sector according to the clock signal.

摘要： Embodiments of the invention efficiently conduct servo corrections for preventing error propagation during SSW. In an example of the present invention, a servo position signal generator generates a servo position signal indicative of the current position of a read element on the basis of a servo signal from a servo channel. A target position generator generates correction data from multiply and add operations between the PES generated when the track that the read element is following is written, and pre-registered correction coefficients. A correction target position is generated from the correction data and a reference target position, and then output to a position error calculator. The position error calculator generates a position error signal (PES) from the servo position signal and the target position signal, and outputs PES to a servo controller. The servo controller generates a control signal (DACOUT) in accordance with PES, and a motor driver unit supplies an electric current of a required value to a VCM in accordance with the control signal.

摘要： The invention reduces power consumption when, for example, a mobile personal computer is in a power-saving mode or when a cellular phone is in a wait mode, in an electro-optical apparatus, such as a liquid crystal display of the subfield drive type used as a display apparatus for various apparatuses. Three different settings “64”, “16” and “2” are enabled as the number of gray scale levels in an electro-optical apparatus, the number of subfields becoming smaller as the number of gray scale levels is reduced. When a large number of gray scale levels is not required (when in the power-saving mode, the wait mode, etc.), a low number of gray scale levels is set, so that the own capacitance of a liquid crystal layer and storage capacitance are charged and discharged less often.

摘要： Disclosed is a polishing system used for polishing a surface to be polished of an object to be polished by a polishing pad, which is capable of improving uniformity of the surface to be polished of the object to be polished by positively, accurately adjusting a polishing pressure, and a polishing method using the polishing system. Concretely, the surface to be polished of a wafer as the object to be polished is polished by relatively moving, along a plane, a polishing surface of the rotating polishing pad and the surface to be polished of the wafer in slide-contact with each other, and adjusting a pressing force applied from the polishing pad to the wafer in accordance with a polishing pressure previously set depending on a relative-positional relationship between the polishing surface of the polishing pad and the surface to be polished of the wafer.
