Abstract: Disclosed herein are a recording medium, an apparatus for forming the recording medium, and an apparatus and method for reproducing the recording medium. CPI (Copy Protection-related Information), identification information (CPI_Flag) indicative of recording or non-recording of the CPI, and/or a plurality of contents specific information (CSI) with different formats are recorded in a PIC (Permanent Information & Control data) zone of a high-density optical disc such as a BD-ROM (Blu-ray Disc-ROM). A formatting operation and mastering operation are performed under the condition that control data including the CPI, CPI_Flag and/or CSI is separated from main data. An optical disc device judges whether the optical disc has been illegally copied, with reference to the CPI, CPI_Flag and/or CSI read from the optical disc, and compulsorily stops a data playback operation upon judging that the disc has been illegally copied.

Abstract: The present invention is directed to a semiconductor memory device and method of operating the same. In case where fail normal word lines of normal word lines from a normal memory block to which fail memory cells are connected is substituted by redundant word lines of a redundant memory block, the redundant word lines to replace the fail normal word lines are set in the redundant memory block. If the fail normal word lines are selected when the device is operated, the fail normal word lines and the redundant word lines are activated at the same time to increase capacitance of a capacitor connected to the sense amplifier. Therefore, it is possible to increase the exactness of a read operation or a refresh operation and improve reliability of a device operation, by increasing a comparable margin of the sense amplifier.

Abstract: The present invention relates to a high-density optical disk having thin film layer made from a thermochromic polymer with a red-shift which exhibits self-focusing and optical bleaching. After an incident light beam passes through the polymer medium, not only can the spot size of the beam be reduced but also transmittance can be enhanced due to these kinds of third-order nonlinear optical response. Thus, a high-density disk structured according to the present invention is capable of the signal reproduction resolution beyond the diffraction limit with an efficient reflectivity. Accordingly, data recording density of a high-density disk can be improved greatly.

Accordingly, efficient DSV control can be achieved for even relatively-long sequences.

Abstract: The present invention relates to method and apparatus of modulating a series of data words into (d,k) constrained sequence in order to record onto a recording medium. The present method generates, for each data word, a number of alternative sequences by combining mutually different digital words with the data word, calculates for each alternative sequence a digital sum value (DSV) and a penalty based on respective consecutive-zeros sections within the sequence and a joining consecutive “zeros” to a previously-selected sequence, and selects one alternative sequence for recording onto a recordable medium based on the calculated DSV and penalties. Owing to the present invention, DC component of sequences to be recorded onto a recording medium is suppressed and stabilization of a reproduction clock is improved through writing more edge information (i.e., “1”s).
