Title: Method and system for recombining spectral reflectance
Inventor: ARAI YOSHIFUMI
IPC: G01J3/46
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To predict and correct fluctuation in the mixing ratio incident to variation in the partial characteristics of base ink only through calculation of a computer by utilizing the information of an original data base effectively. SOLUTION: At a spectral reflectance analyzing section 20, spectral reflectance is decomposed into components thereof, i.e., the spectral reflectance components of several kinds of dye, using multi-variate analysis. The spectral reflectance thus obtained is compared with the spectral reflectance of some dye in the candidate data base of that component and correspondence of each component to the spectral reflectance of dye is identified. Partial component of each identified dye component is then substituted with the component of other dye and the spectral reflectance is rearranged. Furthermore, a new mixing ratio for reproducing the original spectral reflectance accurately is determined by regulating the mixing ratio through optimization.

Title: Optical disk device
Inventor: IIMURA SHINICHIRO
IPC: G11B7/00
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To detect the weaving motion of a groove even during recording and to surely reproduce various pieces of information caused by the weaving motion by generating wobble signals through subtracting the light receiving results of the light receiving surfaces of the inner and outer peripheral sides during data recording, changing the gain in accordance with the levels of the light receiving results and correcting the levels of the light receiving results. SOLUTION: The signal levels of light receiving results I0 and I1 obtained from the light receiving surfaces of inner and outer peripheral sides are corrected by multiplying circuit 24A and 24B of AGC circuits 22A and 22B. Then, peak levels are detected by peak hold circuits 25A and 25B. Then, the gains of the circuits 24A and 24B are connected so that the detected peak levels become a prescribed level. Then, the signal levels of the results I0 and I1 are corrected so that the signal level changes at the results I0 and I1 associated with the raise of the light quantity of laser beams are made equal and a substracting circuit 7A executes a subtraction.  Thus, the mixing of reproduced signals RF into wobble signals WB is suppressed and as a result, a groove weaving is detected even during recording and the information associated with the rotational speed and the position during the weaving is reproduced.
