    摘要： A method and apparatus of converting a series of data words into modulated signals generates for each data word, a number of intermediate sequences by combining mutually different digital words with that data word, scrambles the intermediate sequences to form alternative sequences, translates each alternative sequence into a (d,k) constrained sequence, measures for each (d,k) constrained sequence, not only an inclusion rate of undesired sub-sequence but also a running DSV (Digital Sum Value), and selects one (d,k) constrained sequence having small inclusion rate for recording on an optical or magneto-optical recording medium among the (d,k) constrained sequences having maximum value of running DSV. smaller than a preset limit. Accordingly, efficient DSV control can be achieved for even relatively-long sequences.

    摘要： The present invention relates to method and apparatus of converting a series of data words into modulated signals. This method generates for each data word a number of intermediate sequences by combining mutually different digital words with that data word, scrambles these intermediate sequences, translates each scrambled sequence into a (d,k) constrained sequence, detects running digital sum (RDS) every bit for each translated (d,k) constrained sequence while counting sign changes of each RDS, selects one sequence of which RDS changes most in sign among the (d,k) constrained sequences after discarding every sequence of which maximum value of RDS is beyond a preset threshold, and records the selected sequence onto a recordable medium such as an optical disk or a magneto-optical disk. The present invention can suppress DC component more remarkably in case that a sequence becomes longer.

    摘要： An apparatus, and related method, for recording data that includes a controller to generate control information required to record a main data. The control information including at least one information unit for a specific writing speed and recording layer. The information unit includes write strategy parameters for first write strategy type to be used for the writing speed and recording layer, the first write strategy type being one of an (n−1) write strategy type and an n/2 write strategy type, where n is a length of mark and each type represents a number of write pulse to form a corresponding mark. A writing/reading unit records the control information at a specific area of a recording medium, wherein the controller controls the writing/reading unit to record the control information and to record the main data on the recording layer using write strategy parameters for the first write strategy type included in the information unit, at the specific writing speed.
