  • Patent number: 6104694
    Abstract: The invention relates to a reproduction or recording device for optical recording media with which information, data or control signals are reproduced or recorded without an optical recording medium provided as an exchangeable data medium, such as, for example, a CD or a disk for recording information, being inserted in the device and without a special electronic memory being present. According to the invention, a holding apparatus which is provided in the reproduction or recording device for optical recording media for the purpose of holding the exchangeable data medium is designed as an optical recording medium. The holding apparatus, which is driven by the disk turntable even when there is no optical recording medium inserted, is designed as an optical recording medium. The holdin apparatus has an optical recording medium which is designated as puck CD and, in contrast to the exchangeable data medium, is a component part of the device.
