Publication number: 20070033602Abstract: In the case of a disk with a high NA which enables high-density recording, since the coma aberration increases as the numerical aperture, NA, increases, a disk protective layer needs to be thin very much, and a damage or scratch imparted to a surface of the disk affects largely the record and reproduction of data. An object of the invention is to reduce the generation of damage to a storage disk due to a collision between a lens holder or an objective lens and the storage disk. With a view to attaining the object, according to the invention, a longitudinal direction of a protector 11 provided on a holder is made substantially parallel to a straight line which connects the rotational center of a motor with the center of an objective member.Type: ApplicationFiled: July 31, 2006Publication date: February 8, 2007Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Yota Hashimoto, Yoshihiro Kiyomura, Junya Aso, Seiro Shimoda
