摘要： A miniaturized optical disk apparatus which performs a pull-in of a focus servo and a pull-in of a tracking servo without a position detector for detecting an optical head. If the optical head is located at a non-reflection film area and thus the focus servo cannot be performed, then the optical head is moved and the focus servo is performed again. This process is repeated until the focus servo can be achieved. In addition, if the optical head is located at a non-track area, then the optical disk is moved to a track area and then the tracking servo is performed. This process also repeated until the optical head is located over the track area. The tracking servo can be stably performed since it is performed only when the optical head is located over the track area. The present invention is applicable to the optical disk apparatus which uses a 3.5 in optical disk.
摘要翻译：执行聚焦伺服的引入和跟踪伺服的拉入的小型化光盘装置，而没有用于检测光学头的位置检测器。如果光头位于非反射膜区域，因此不能执行聚焦伺服，则移动光头并再次执行聚焦伺服。重复该过程，直到可以实现聚焦伺服。此外，如果光头位于非轨道区域，则将光盘移动到轨道区域，然后执行跟踪伺服。该过程也重复，直到光学头位于轨道区域上方。由于仅当光头位于轨道区域上方时才执行跟踪伺服，所以可以稳定地执行跟踪伺服。本发明适用于在光盘中使用3.5的光盘装置。

摘要： In an optical disk storage, the seek of an optical head is controlled so that the number of seek times cannot exceed a threshold number of times in a predetermined period or an accumulated seek period cannot exceed a threshold period in a predetermined period. Therefore, a wasteful power consumption and a rise in the internal temperature associated with the seek activity can be effectively prevented.

摘要： To detect an MSK modulation mark from an MSK-modulated wobble signal without fail. A wobble signal of an optical disk is supplied to an address decoding circuit. The address decoding circuit performs exclusive-OR operation of a binarized wobble signal and a reference clock signal generated from the wobble signal by an PLL circuit, to thus compute a proportion of the exclusive-OR result assuming a value of one every half period of a reference clock signal. When there are continuously present a predetermined number of sections or more where a proportion becomes a predetermined threshold proportion or more, the sections are detected as an MSK modulation mark. A system controller changes the threshold proportion in accordance with crosstalk from an adjacent track.

摘要： A high-definition optical disk and a high-definition optical disk drive, which record data on lands and grooves. Wobbles are formed in grooves and lands of an optical disk, and address information is embedded in the wobbles. The wobbles are formed so as to become in phase with each other in the grooves. An address of the land sandwiched between the grooves is detected from the wobble of the groove. When the wobble of the land is not an in-phase wobble but is of opposite phase, a gray code of the wobble is substituted with a binary address such that 0 is achieved when the gray code is converted into the binary address. As a result, even in the case of the wobble of opposite phase, the address information about the land is made coincident with address information about an inner-radius-side adjacent groove, thereby determining address information about the land.

摘要： An optical disk device which drives HD-DVD or the like. In an HD-DVD type optical disk, address information is embedded in four wobble waves having the same phase. A wobble signal is detected by an optical pickup and demodulated by an address decoding circuit. The address decoding circuit detects an amount of phase difference of the wobble signal. The system controller sets an error flag in a bit in which the detected amount of phase difference exceeds a predetermined range. When a reading error is determined by means of CRC or the like, bit data replacement is performed with regard to the bit in which an error flag has been set, thereby correcting the error.
