    • The optical disk apparatus is provided with a Viterbi decoder and an expected value correction circuit. The branch metric operation unit calculates first, second and third errors between sampling data and expected values, and outputs them to the expected value correction circuit. The expected value correction circuit extracts the sampling data in a region where its variation is small based on the first, second and third errors, calculates the average values of the extracted sampling data to correct the first, second and third expected values, and outputs the corrected expected values to the branch metric operation unit. The Viterbi decoder performs Viterbi decoding of the sampling data based on the first, second and third corrected expected values. Thus, high-precision Viterbi decoding is permitted even if the amplitude value of the reproduction signal varies.

    • A digital signal processor (1045) arithmetically determines a comparison level for comparing each signal component by determining a comparison level of comparators (1033 and 1034) for comparing a fine clock mark signal such that a larger weight is assigned to the comparison level of the signal component already compared. The comparators (1033 and 1034) compare the fine clock mark signal with reference to a level set on a peak side and a level set on a bottom side. When digital signal processor (1045) receives the comparison signal from one of the comparators (1033 and 1034) prior to the comparison signal sent from the other, the digital signal processor produces a fine clock mark detection signal FCMT based on the comparison signal sent from a comparator (1047). Thereby, the clock can be accurately produced based on the fine clock mark signal even when a signal component having a larger amplitude than that of the fine clock mark signal is detected.
    • 数字信号处理器(1045)通过确定用于比较精细时钟标记信号的比较器(1033和1034)的比较电平来算术地确定比较每个信号分量的比较电平,使得较大的权重被分配给信号的比较电平 组件已经比较。 比较器(1033和1034)将精细时钟标记信号与在峰值侧设置的电平和在底侧设置的电平进行比较。 当数字信号处理器(1045)在从另一个发送的比较信号之前从比较器(1033和1034)之一接收到比较信号时,数字信号处理器基于从...发送的比较信号产生精确的时钟标记检测信号FCMT 比较器(1047)。 因此,即使当检测到具有比精细时钟标记信号的幅度大的信号分量时,也可以基于精细时钟标记信号精确地产生时钟。

    • The present invention aims at providing an information recording and reproducing device which cannot only maintain interchangeability with the reproducing dedicated type media but also realize enhancement of reliability of media based on spare processing as appropriate. A spare area is selectively secured in accordance with whether or not an instruction indicating that a spare area is secured is detected. The instruction indicating that a spare area is secured, for example, is issued by utilizing a method in which a user directly selects whether or not data is recorded in a high reliability mode to set the selection results, or the like. When first recording processing is started, firstly, after an area for recording of a data block for first lead-in is secured in an unrecorded area, first user data is recorded from a position next thereto. When a reproducing defect is detected in verifying reproducing of recording data, a first spare area is secured in an outer periphery of a write once type disc and a spare processing object data block is recorded therein.
