摘要： An evaluation method for calculating an identification signal by using PRML, comprises a table storing true patterns and ideal signals thereof, false patterns corresponding to the true patterns and ideal signals thereof, and Euclidean distance between the true pattern and the false pattern, a calculating unit, when a recording signal synchronized with an identification signal coincides with any pattern of the table, calculates a distance between Euclidean distance between the ideal signal of the true pattern and a reproduction signal and Euclidean distance between the ideal signal of the false pattern and a reproduction signal, and an evaluation unit which evaluates an identification signal by using an average and standard deviation of difference. A table for patterns is created for a likely mistaken pattern, whereby calculating an evaluation value with high precision, of a signal quality, with a small amount of calculation.

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： A magnetic scale includes a pipe and a polarizable magnetic member closely attached to the inner surface of the pipe so as to extend in the longitudinal direction of the pipe. The magnetic member is formed with magnetic marks provided by a plurality of N poles and S poles alternately arranged in the longitudinal direction of the magnetic member. Accordingly, the magnetic member can be reliably protected to thereby improve its durability.

摘要： A magnetic scale is disclosed wherein a magnetic member is protected with certainty to effectively enhance the durability. The magnetic scale includes a magnetic member provided between outside and inside pipe members and has magnetic graduations magnetized alternately with the N and S poles along the extending direction thereof. When the magnetic member and the inside pipe member are assembled in the outside pipe member, the inside pipe member contacts partly with an inner face of the outside pipe member and partly with a back face of the magnetic member in such a manner as to cover the overall back face. The outer face of the inside pipe member presses the back face of the magnetic member over the overall length so that the close contact face of the magnetic member is closely contacted with the inner face of the outside pipe member.
