摘要： Information recorded on an optical disk in accordance with a mark edge recording scheme is detected by a center detection circuit which includes a bisected beam detector to obtain a mark center position signal. In succession, the mark center position signal is converted to a mark edge position signal by an edge signal generating circuit. An information reproducing device is implemented which is capable of performing reproducing operation on an information medium conforming to a high-density mark edge recording scheme and which is stable against changes of recording paper, recording sensitivity and reflectivity.

摘要： An optical pickup lens focuses laser beams having different wavelengths λ1, λ2 and λ3 on at least three kinds of optical discs. At least one side of the optical pickup lens has a concentric loop zonal structure for compensating wavefront aberration occurring when recording or reproducing an optical disc having a substrate thickness t1 by the laser beam having the wavelength λ1 and wavefront aberration occurring when recording or reproducing an optical disc having a substrate thickness t2 by the laser beam having the wavelength λ2. When recording or reproducing an optical disc having a substrate thickness t3 by the laser beam having the wavelength λ3, a phase difference given to the laser beam having the wavelength λ3 due to the concentric loop zonal structure is about 0.15 λ or smaller.

摘要： An information recording medium, an information recording/reproduction head, and an information storage device are provided for performing a track servo operation at a smaller track pitch than that conventionally used without reducing the widths of servo burst patterns. The widths of servo burst patterns (107, 108, 109, 110) are increased over a track pitch (TP) and the end of the servo burst pattern is disposed so as not to coincide with a center line (111) of an information track. In addition, a servo magnetic head (112) and a reproduction magnetic head (113) are implemented in one magnetoresistance element (159).
