    摘要: A mark having a length nT (n being an integer equal to or greater than 3 and T being a clock period) is formed by modulating irradiation laser power with three values of recording power Pw, erase power Pe, and bias power Pb (Pw>Pe>Pb). Constant strength periods (At) of the recording power Pw are set as AtT, A1T, . . . , and AmT and constant strength periods (Bt) of the bias power Pb are set as BtT, B1T, . . . , BmT, and CT (C=−1 to 3). The application of laser is divided into pulses in order of AtT, BtT, A1T, B1T, . . . , AmT, BmT, and CT (m=(n−k)/2, k=3 (if n is an odd number), or k=4 (if n is an even number)). (Here, the constant strength period of the recording power Pw for n=3, n=4, n≧5 (odd number), and n≧6 (even number) is set as At3, At4, Atod, and Atev, the constant strength period of the bias power Pb for n=3, n=4, n≧5 (odd number), and n≧6 (even number) is set as Bt3, Bt4, Btod, and Btev, and then, At3+Bt3=Atod+Btod=Am+Bm=2T and At4+Bt4=Atev+Btev=3T).

    摘要: Provided is a method and an apparatus for setting a virtual disc status of an optical disc drive. While set to the virtual disc status, the optical disc drive does not detect if an optical disc is present in the optical disc drive in response to the optical disc drive being powered on. Accordingly, power may be consumed and noise may be reduced.

    摘要: A hard disk drive includes a chassis which supports a “sealed” housing containing a data storage magnetic disk, and read/write heads and actuator. The housing also contains an erasure device which generates a magnetic or other field or emanation for erasing the disk, so that the erasing field or emanation need not penetrate the sealed housing to effectuate erasure. A backup power supply provides power to the erasing device so that erasure can occur even in the absence of external power. A bus- or network-actuated arrangement couples power to the erasure device so that many hard drives may be simultaneously erased.

    摘要: The optical disk device can stably control an aberration correction lens even when one end of a movable range of the aberration correction lens is set as a reference position. The optical disk device comprises an optical pickup unit including the aberration correction lens and a stepping motor for moving the aberration correction lens, wherein, when an optical disk is inserted into the optical disk device, the aberration correction lens is moved to the reference position within the movable range and near one end thereof, and wherein, when moving the aberration correction lens to the reference position, driving pulses are applied to the stepping motor to press the aberration correction lens against the one end of the movable range, and thereafter a predetermined number of pulses are applied to reversely rotate the stepping motor and to set a stop position where the aberration correction lens stops as the reference position.

The method comprised: a) performing a plurality of writing actions in which a plurality of data portions are written to the disc, b) performing a plurality of verification actions in which written data portions are at least partly verified and at least part of the data portions are replaced if needed. The method further comprises a2) performing a decision action for each writing action in which a decision whether or not to perform the verification action for a specific written data portion is taken.
