摘要： User data may be encoded into codevectors as follows. A first block of data symbols is generated by arranging a predetermined number of user data symbols and a predetermined number of dummy data symbols in a predetermined order. The first block of data symbols is encoded using an ECC encoder to obtain a codeword having a predetermined number of symbols, the codeword comprising the first block of data symbols and a second block of parity symbols. Then a codevector is generated containing less then all the user data symbols and parity symbols from the codeword. The codevector can be stored or transmitted. The codevector may be decoded by generating a codeword comprising dummy data symbols, a codevector, and filling symbols, arranged in a predetermined order. Then decoding the codeword using an ECC decoder to obtain the user data symbols.

摘要： When writing data to an optic disc with a constant linear velocity, and encountering a disc error, data is written into the defect management area of the disc without changing the rotational speed of the disc, or at least without changing the rotational speed of the disc sufficiently to maintain a constant linear velocity. This allows an increase in the rate at which data may be written to the optical disc. It also avoids or reduces the need for the rotational speed of the disc to be changed, which allows a further improvement in the time taken to write data to the disc. In order to continue writing data to the disc without changing the rotational speed, the data rate must be increased while writing to the defect management area. For this to be possible, the data must be written into an “iced” or unformatted part of the defect management area.
摘要翻译：当以恒定的线速度向光盘写数据并且遇到盘错误时，将数据写入盘的缺陷管理区而不改变盘的转速，或者至少不改变盘的转速足以保持恒定的线速度。这允许数据可以写入光盘的速率的增加。它还避免或减少了要改变盘的旋转速度的需要，这允许进一步改进向盘写入数据所需的时间。为了在不改变转速的情况下继续将数据写入盘中，必须在写入缺陷管理区域时增加数据速率。为了可以这样做，数据必须写入缺陷管理区域的“冰”或非格式化部分。

摘要： A wobble signal is generated from at least two elementary signals (A,B,C,D) detected by scanning a wobbled track of a data carrier. The invention proposes a solution for eliminating the noise of various origins in the wobble signal, notably the high frequency data leakage into the wobble signal due to radial asymmetry introduced in the diffraction pattern on the detector, whatever the reason for this radial asymmetry. According to the invention, the at least two elementary signals are filtered with at least an adaptive filter (40), and said filtered elementary signals are subtracted (44) from said wobble signal (PP) thereby generating an improved wobble signal.

摘要： A record carrier has a servo track indicating an information track intended for recording information blocks, which servo track has a variation of a physical parameter, referred to as wobble. The wobble is modulated for encoding record carrier information, such as addresses. The servo track is subdivided in non-modulated and parts modulated parts in which the frequency and/or phase of the variation deviates from the wobble frequency. The slope of the wobble is substantially continuous at transitions between the modulated and non-modulated parts by using wobbles starting at the maxima or minima of the wobble.

In order to be able to use the same ECC decoder for decoding of more than one type of data a method of encoding is proposed comprising the steps of: generating a first block of a fixed first number of data symbols by taking a fixed second number, being smaller than said first number, of user data symbols, and a fixed third number of dummy data symbols, and by arranging said user data symbols and said dummy data symbols in a predetermined order, encoding said first block of data symbols using an ECC encoder (2) to obtain a codeword having a fixed number of symbols, said codeword comprising said first block of data symbols and a second block of a fixed forth number of parity symbols, and generating a codevector by selecting a fifth predetermined number of user data symbols and a sixth predetermined number of parity symbols from said codeword, the sum of said fifth and sixth number being predetermined and smaller than the sum of said second and forth number.
