摘要： Reproduced signals are equalized by the least square technique by using a predetermined number of data samples binarized by a Viterbi decoder. Even when data written on an optical disk is unknown, the data can be equalized in a stable manner and can be reproduced at a low error rate without instability factors such as divergence due to interference.

摘要： Address information is formed by M wobbles (integer M is the number of wobble waves) per bit as a basic unit, and is NRZ-recorded. Also, a sync signal used in sync detection of the address information is formed by N wobbles per bit as a basic unit (integer N is the number of wobble waves and M=2N). The sync signal with such configuration (6 wobbles per bit) is recorded on the head side of the address information (12 wobbles per bit). In this way, even when external noise is large, a modulated wobble signal can be demodulated more accurately.
摘要翻译：地址信息由每个位的M个摆动（整数M是摆动波数）作为基本单位形成，并且被NRZ记录。此外，用于地址信息的同步检测的同步信号由每位N个摆动形成为基本单位（整数N是摆动波数，M = 2N）。具有这种配置的同步信号（每位6个摆动）被记录在地址信息的头侧（每位12个摆动）。以这种方式，即使当外部噪声大时，可以更精确地解调调制的摆动信号。
