Abstract:
An apparatus for at least recording information on or reproducing information from a card recording medium having an optical recording region including a track, an IC memory region and a communication antenna coil connected to said IC memory region, said apparatus comprising:an optical head for irradiating the optical recording region of the medium with a beam of light through an objective lens; a drive mechanism comprising a coil and a magnet for driving the objective lens along a tracking direction and/or focusing direction; a control circuit for controlling said drive mechanism in order to exert at least tracking control or focusing control on the beam of light; an apparatus-side antenna coil arranged opposite to the antenna coil of the medium; a reader/writer for at least storing information in or reading information from the IC memory region of the medium through transmission of information by means of electromagnetic induction between said antenna coil of the medium and said apparatus-side antenna coil; and a processing circuit for controlling the operation of said optical head, said drive mechanism, said control circuit, and said reader/writer, said processing circuit prohibiting said reader/writer from storing information in or reading information from the IC memory region of the medium during the period where said control circuit is exerting at least tracking control or focusing control on the beam of light.
