Title: Optical disk device
Inventor: SOMA YASUTO
IPC: G11B7/085
Filed: 1992-07-09
Abstract: PURPOSE:To prevent unstability in drawing operation due to a pseudo S-shape curve caused by a disk surface at a focus drawing time when a focus error signal is normalized with total reflection light quantity in a recording type optical disk device. CONSTITUTION:In a recording type optical disk, the intensity of beams at a recording time and at a reproducing time are different from each other, and the values as well of the focus error signals vary according to that. By using a divider 15 for preventing that, a ratio between the magnitudes of the total reflection light quantity and the error signal is taken, and a servo is applied by using the ratio. At a focus servo drawing time, by a controller 17, the value of a denominator in the divider 15 is fixed to a prescribed value, influence by a pseudo focus error signal due to the optical disk surface is reduced, and focus servo drawing is per formed stably.

The transfer functions of the highlighting filters and the blocking filter are set at the respective highlighting and blocking filters F1 and F2 so that the transfer functions are internally present as the quotient patterns. A data processing means 4 monitors the data after passing the respective highlighting and blocking filters F1 and F2 at the voltage level in real time. When the voltage level of the data is higher than a preset level, the acceptance of the original data is continued as the data including the significant signal. When the data become lower than the preset level, the background noises are accepted.  Thus, the characteristic quantity is extracted.
