    摘要： An optical disk writing apparatus maintaining appropriate write power in real time with a simple configuration includes a buffer for recording data, a binarization circuit supplying data to the buffer, an LD writing data recorded in the buffer onto a DVD disk, a detector reading out from the DVD disk a signal representing data written by the LD at an arbitrary time during a period starting from when the amount of data recorded in the buffer and not yet written onto the DVD disk becomes zero until the amount of data reaches a predetermined number of ECC blocks, and a servo processor correcting an error in the data read out by the detector for every data amount susceptible to error correction at one time, evaluating the writing of the LD using the corrected signal, and controlling the energy density to be employed in writing data onto the DVD disk by the LD according to its own evaluation.

    摘要： When recording the picture data or voice data on the hard disk, the encrypted data is generated through the encryption process with the serial number as the key based on the file system, and the encrypted data is recorded on the hard disk. When powered on, the encrypted data is read from the hard disk, the decoded data is generated with the serial number as the key, and the decoded data is determined whether normal or not. If normal, the data can be reproduced, and if abnormal, the data cannot be reproduced.

    摘要： An optical disc device includes a recording power acquiring unit that finds an optimum recording power when data is written in a data area by writing data for calibration in a power calibration area, and a data writing unit that writes data in a data area to be written by using an optimum recording power found by the recording power acquiring unit. A method for acquiring an optimum recording power used by the recording power acquiring unit when an area to be written is a not-yet-recorded area is different from a method for an already recorded area. When an area to be written is a not-yet-recorded area, the recording power acquiring unit finds an optimum recording power. When an area to be written is an already recorded area, the recording power acquiring unit writes preliminary data in a power calibration area and finds an optimum recording power.
