Abstract: An integrated circuit for a CD player includes an EFM decoder which converts an EFM signal inputted from a compact disc into symbols. Subcode data which includes first, second and third areas is outputted from the EFM decoder and stored in a first shift register. Data in the first area of the subcodes can be wholly stored in a memory circuit which is controlled on the basis of data in the second area of the subcodes and a signal applied from an external source, for example, a microcomputer by an R/W control circuit. Data in the third area of the subcodes is applied to the memory circuit as a writing address and address data inputted from the microcomputer is applied to the memory circuit as a reading address. One of data read from the memory circuit and data of the subcodes is selectively outputted from a selector to a second shift register which outputs the inputted data in response to clocks from the microcomputer to the same in a bit-serial fashion.

Abstract: An apparatus for rotatively driving a turn table comprising a motor including a rotor having an arrangement of a plurality of permanent magnet poles such that north and the south poles are alternately disposed in a circle on the turn table and a stator provided to be opposed to the arrangement of the permanent magnet poles and including three stator pole means for electromagnetically driving the rotor, three saturable core coils provided to be opposed to the rotor and disposed to bring about a phase difference of 120.degree.
