摘要： An apparatus and a method removing offset of a Phase Lock Loop (PLL) circuit in a disc drive without using a disc when data playback is performed, the apparatus including an ENDEC module and a PLL circuit. The ENDEC module outputs a binary signal if an offset removal mode is set. The PLL circuit removes the offset of the PLL circuit by comparing a phase of the binary signal with a phase of a channel bit clock signal. Therefore, a time to remove the offset of the PLL circuit is reduced and the possibility not to remove the offset of the PLL circuit due to a damaged disc is prevented.

摘要翻译： 该装置和方法在执行数据重放时不使用盘来去除磁盘驱动器中的锁相环（PLL）电路的偏移，该装置包括ENDEC模块和PLL电路。 如果设置了偏移消除模式，则ENDEC模块将输出二进制信号。 PLL电路通过将二进制信号的相位与通道位时钟信号的相位进行比较来消除PLL电路的偏移。 因此，减少了消除PLL电路的偏移的时间，并且防止了由于损坏的盘而导致的PLL电路偏移的可能性。

摘要： A method of designating a disk recording capacity and an optical disk recording apparatus using the method, where a maximum recording capacity is designated by measuring an external disturbance for disk regions. The method of designating a disk recording capacity includes: partitioning a disk into a plurality of disk regions, and measuring external disturbance at the disk regions; setting a disk speed based on the measured external disturbance, and designating disk regions excluding the disk regions where the external disturbance is measured as recordable disk regions; and calculating a maximum disk recording capacity based on the designated recordable disk regions.

摘要： A tilt adjusting apparatus including a digital signal processor, a first drive integrated circuit, and a tilt adjuster. When an optical recording medium is loaded into a deck, the digital signal processor outputs a focus control signal to control a focus of an optical recording medium, measures a tilt with respect to the optical recording medium, and outputs a tilt adjustment signal and a switch control signal so as to adjust the tilt. The first drive integrated circuit either synthesizes the tilt adjustment signal and the focus control signal or receives only the focus control signal according to the switch control signal and then outputs the synthesized signal or the focus control signal to the optical pickup. The tilt adjuster synthesizes the tilt adjustment signal output from the first drive integrated circuit and the focus control signal and then outputs the synthesized signal to the optical pickup.
