Title: Tracking system for optical disk
Inventor: OTAKE MASATOSHI
IPC: G11B7/095
Filed: 1990-02-28
Abstract: PURPOSE:To attain a composite tracking system always suppressing a tracking shear by delaying the convergence of a correction signal due to the OFF operation of a forecasting correcting system from the response speed of a wobbling tracking system. CONSTITUTION:A capacitor C and a resistor R connected to the output side of a switch 31 for turning on/off the forecasting correction coefficient of a feedforward system using a stored optimum correction value to be added to a push-pull tracking system act as a discharge loop having a time constant set up as a time delayed from the response speed of the wobbling tracking system only when the switch 31 is OFF and the correction coefficient of the forecasting correction system acts so as to be gradually converged always in the zero direction. Even if the response speed of the wobbling tracking system is slow, the correction coefficient is converted upon zero at a speed relatively slower than the response speed, so that a laser beam is always guided to the center of tracks.

Title: Magnetic record erasing circuit
Inventor: KAWAKAMI KAZUKUNI
IPC: G11B5/024
Filed: 1985-03-09
Abstract: PURPOSE:To erase records effectively up to such degree that write is sufficiently possible, by recording a swept carrier wave in recording units of a recording medium. CONSTITUTION:In case that records are confirmed on a monitor device 84 and are erased, an erase key on an operation part 104 is operated. A control circuit 12 outputs an erase signal 204, which is held in the low level for a time corresponding to a prescribed pulse width T, to a control line 92, and a switch 52 is switched to the connection state opposite to that shown in the figure. An erase signal generating circuit 202 increases the supply current to a terminal #12 of an integrated circuit 200 by the erase signal 204, and the integrated circuit 200 generates an erase carrier wave whose frequency is swept from 4.5MHz to 20MHz. This erase carrier wave is supplied to a magnetic head 56 from a terminal 30 through an HPF 32, a synthesizing circuit 34, a recording amplifier 84, and the closed switch 52. Thus, this erase carrier wave is recorded over an already recorded video signal on a pertinent track.

Title: Frequency synthesizer
Inventor: SAGAWA MORIKAZU
IPC: H03L7/18
Filed: 1984-03-09
Abstract: PURPOSE:To attain stable operation over a broad band even at a high frequency region and to decrease power consumption by adopting the PLL circuit constitution provided with an analog frequency divider added with a feedback circuit and a means for varying a bias voltage of the frequency divider by an output of a loop filter. CONSTITUTION:The anlog frequency divider 20 utilizes the parametric operation due to the nonlinearity of a capacitor between terminals of a diode D31 and the mixer operation to continue it and is operated with low consumption even at a high frequency region. Since the frequency divider 20 takes charge of the high speed operation, a prescaler 21 saves a frequency divider operated in a high speed and having large power consumption. When the bias voltage to the frequency divider 20 is changed in response to an input frequency as the bias voltage is decreased with the higher input frequency, the frequency dividing band is widened. Then the frequency synthesizer with a broad band and less power consumption is realized by providing a voltage controller 22 changing the bias voltage of the frequency divider 20 in response to the output voltage of a filter 12. In this case, the output of the voltage controller 22 is connected to a terminal 33 of the frequency divider 20a and the bias voltage of the frequency divider is changed as stated above.
