Title: Optical device
Inventor: SHIMOZONO HIROAKI
IPC: G11B7/135
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To achieve good productivity, miniaturizing, light-weighting, and high precision of a device by setting an object lens so that its aberration is corrected in accordance with a specification of a protection layer of an assumed optical disk, and making a difference between object-to-image distances for proper aberration into a specific range in the case of recording or reproducing a 1st- and a 2nd optical disks. SOLUTION: In the case of recording or reproducing a 1st- and a 2nd optical disks, a difference between object-to-image distances for proper aberration is made to less than 2 mm. When varying a distance between the object and image, it is desirable to vary also an operation distance (a distance from the object lens surface on the optical disk side up to the optical disk surface on the object lens side). This operation is for the purpose of recording or reproducing data on an information recording surface with fidelity by precisely focusing light from a light source on an information recording surface of an optical disk, and irradiating a light receiving element 30 with the reflected light from the information recording surface through an object lens.
