摘要： An integrated circuit includes: a signal processor, which receives an input signal and generates a processed signal, representing processing information obtained by subjecting the input signal to predetermined processing, and at least one type of internal signal including internal information obtained during the processing; at least one memory storing the processing information; an interface exchanges signals with an external device; and a controller controlling the signal processor, memory and interface. On receiving a first instruction from the external device through the interface, the controller controls the signal processor and memory such that the processing information is once stored in the memory and then output to the external device via the interface. In response to a second instruction, the controller controls the signal processor and memory such that the internal information is once stored in the memory and then output to the external device via the interface.

摘要： A signal evaluation method according to the present invention is a method for evaluating a read signal, retrieved from an information recording medium, based on a binarized signal generated from the read signal by a PRML method. The method includes the steps of: detecting the patterns of multiple paths associated with the binarized signal and merging into the same state; getting the ideal value of a correct pattern associated with the binarized signal and that of an erroneous pattern that is similar to, but different from, the correct pattern; calculating the difference between a distance from the ideal value of the correct pattern to the read signal and a distance from that of the erroneous pattern to the read signal; calculating, based on the difference, an expected error rate for each predetermined group of patterns by the PRML method; and calculating a standard deviation that is associated with a total error rate, which is obtained by adding together the error rates of the predetermined groups of patterns, and that is used for evaluating the read signal.
