    • With an optical disc device for reproducing information from discs having a recording density different from one another, by means of laser light beams each having a wavelength different from one another, a provision is put in place to prevent data stored on a CD-R disc from being damaged by irradiating a short wavelength laser beam. A method for identifying discs disclosed by the present invention is to find out whether or not a disc in question is CD-R and the like by irradiating long wavelength laser light on the disc while the rotation of the disc is suspended, and otherwise to find out whether or not a disc is DVD and the like by irradiating short wavelength laser light on the disc. Shifting a focusing lens in the light irradiating axis direction of laser light by means of an actuator generates a focus error signal and an all light amount sum signal, the amplitudes of which enable the identification of discs.

    • A dual-tone multiple-frequency (DTMF)-signal generating apparatus of the present invention is provided with a high-group frequency divider and a low-group frequency divider for dividing a reference frequency signal into high-group frequencies and low-group frequencies, respectively. The respective outputs from the high-group divider and the low-group divider are supplied to a high-group-sine-wave-signal generator and a low-group-sine-wave-signal generator. The high- and low-group-sine-wave-signal generators comprise a plurality of bi-stable circuits and include shift registers for sequentially shifting a divided input signal within a predetermined period, a plurality of switches which selectively pass high or low level signal corresponding to the outputs of the respective bi-stable circuits, and a plurality of capacitive elements in which the terminals on one side thereof are supplied with the high or low level passed by the plurality of switches, and the terminals on the other side thereof are commonly connected, the high or low level being applied to the comon connection for every cycle of the shift registers to produce the high- and low-group-sine-wave signals from the common connection. The respective sine wave signals are level converting by a high-group level converter comprising a capacitor and a switch and by a low-group level converter comprising a capacitor and a switch. The level converted high- and low-group-sine-wave signals are combined by a mixer comprising buffer amplifiers, resistors and a transistor, thereby obtaining a DTMF signal.
