PROBLEM TO BE SOLVED: To provide a storage apparatus capable of efficiently correcting variation of baseline. SOLUTION: A read channel 32 is constituted of a variable gain amplifier 311, a low pass filter 312, an AGC 317, an analog/digital converter 313, a frequency synthesizer 314, a filter 315, a soft output detection part 320, an LDPC decoding part 322, a synchronizing signal detection part 321, a run length controlled decoding part 323, a descrambler 324, and a first baseline variation correction part 330. The first baseline variation correction part 330 corrects variation of baseline by feedforward control. COPYRIGHT: (C)2007,JPO&INPIT
