Abstract:
There is provided a signal processing apparatus and a signal processing method capable of allowing data recorded at a high density to be robustly reproduced. A frame sync (FS) is restored by performing maximum likelihood decoding of the FS according to a time-varying trellis with a state and a state transition being limited according to a time, in maximum likelihood decoding of a reproduction signal reproduced from a disk-shaped recording medium, the FS representing a head of a frame, the FS of the frame being arranged at the head of the frame, the FS being recorded at the same positions in a track direction in two adjacent tracks.

Claim (Index 7):
The signal processing apparatus according to  claim 1 ,\n wherein the restoration unit includes an add-compare-select (ACS) unit that obtains a candidate of a state metric of a state of a current time, with respect to each of one or more one-time-preceding state, by adding the state metric of the state and a branch metric of a branch to the state of the current time, selects the state metric of the state of the current time from the candidate of the state metric, and selects a surviving path surviving up to the state of the current time from the surviving path up to each of one or more one-time-preceding states, and the selection of the state metric of the state of the current time and the selection of the surviving path surviving up to the state of the current time are controlled according to a limitation signal limiting the time-varying trellis generated according to a time based on the FS as a reference.
