摘要： A mark corresponding to recording data is formed on an optical disk by: encoding the recording data in accordance with a modulation code and generating encoded data; classifying the encoded data by a combination of at least two of a mark length of a mark, a space length of a preceding space, the mark length of a preceding mark, and the space length of a succeeding space; setting a correction amount for adjusting the position of the start edge and the end edge of a recording pulse based on an evaluation index of a decoding result, which is a result of decoding a reproduction signal of the encoded data, for each of the classification; and generating the recording pulse corresponding to the encoded data by using the correction amount corresponding to the classification of the run length of the encoded data.

摘要： A current detection device includes: a core to be disposed in the vicinity of a conductor as a detection target; a winding wound around the core; an excitation unit configured to apply an excitation signal, having a magnitude and a direction that change at a constant period, to the winding; a magnetic flux detection unit (comparator and averaging circuit) configured to detect a magnetic flux generated in the core due to current flowing through the conductor; and an adder unit configured to add a feedback signal to the excitation signal such that the magnetic flux detected by the magnetic flux detection unit is cancelled.
