    摘要: A rotary recording medium has information signals recorded on a spiral or concentric tracks formed thereon as variations in geometrical configuration. The tracks comprise a mixture of digital recorded tracks which are recorded with a first modulated signal and analog recorded tracks which are recorded with a second modulated signal. The first modulated signal is a digital signal which has been time-sequentially multiplexed in terms of blocks at a transmission frequency of 44.1 kHz or a frequency extremely close to 44.1 kHz and has then been subjected to a modulation, where each of the blocks are constituted by a synchronizing signal, error correcting codes, and an error detecting code, which are added to a plurality of channels of digital data which are digitally modulated information signals. The second modulated signal is an analog modulated analog information signal at least including a composite video signal. A number of blocks recorded in one track turn of the digital recorded tracks is approximately equal to a product of the transmission frequency and a duration of one revolution of the rotary recording medium.

    摘要: In a circuit arrangement for a disk player of the type arranged to reproduce information prerecorded in the form of pits, a variable gain circuit for changing the frequency characteristic of the reproduced signal is provided. The level of the reproduced signal is detected at high and low frequencies so as to produce a control signal the voltage of which varies in accordance with the difference between the level of the high frequency signal component and the level of the low frequency component. The control signal is then applied to the variable gain circuit receiving the reproduced signal so that the frequency characteristic of the reproduced signal will be controlled. Thus, the level of the reproduced signal is boosted at its high frequency range.
