There is provided an information reproduction apparatus that can suppress
degradations in the qualities of reproduced data and timing from due to
interpolation errors when performing interpolation timing recovery, and
that can avoid degradation in the stability of the system due to an
increase in the timing recovery loop delay. An information reproduction
apparatus (100) for reproducing data and timing from an analog signal
including data information and timing information is provided with an
expected value generator (106) for outputting plural expected values, and
a maximum likelihood detector (107) for outputting data that corresponds
to a sequence of the highest likelihood with an output sequence of an A/D
converter among the plural expected value sequences, at the timing of a
second clock.
