PROBLEM TO BE SOLVED: To provide an optical device which has high productivity and is excellent in antireflection characteristic, to provide a manufacturing method of the optical device, to provide a duplicate substrate for preparing the optical device, and to provide a manufacturing method of the duplicate substrate. SOLUTION: On a base surface of the optical device, a large number of structures comprising protruded parts or recessed parts are disposed with a fine pitch of a light wavelength or less. Each structure forms a plurality of lines of circular-arcuate tracks on the base surface and, at the same time, forms a square grid pattern or a quasi-square grid pattern among adjoining three lines of circular-arcuate tracks.

PROBLEM TO BE SOLVED: To reduce an increase in access time caused by the adjustment of focal points on lands and grooves. SOLUTION: This optical recording medium 1 has the lands Ld and the grooves Gv which are alternately formed. The groove Gv has grooves 2b at both ends of its bottom surface and the land Ld has a groove 2a at its center. The bottom surface of the groove 2a of the land Ld and a flat surface 2c between the grooves 2b of the groove Gv are made to be in the same flat surface. The separate adjustment of the focal point in the land Ld and the groove Gv is not needed by using the bottom surface of the groove 2a of the land Ld and the flat surface 2c between the grooves 2b of the groove Gv as track surfaces.

PROBLEM TO BE SOLVED: To obtain a CTS signal in such an amount of signal that can be used for a seak operation and a tracking servo even if the ratio of groove width to a track pitch is about 50%. SOLUTION: Deep grooves 6a and 6b having 50 to 58% ratio of the groove width / the track pitch and shallow grooves 7a and 7b formed at the nearly center of a land and having a V-shaped section are formed on a magneto-optical disk so as to be adjacently disposed. The deep grooves 6a and 6b are wobbled and data are recorded in only the deep grooves. The shallow grooves 7a and 7b are formed in the nearly center position of the land so as not to be wobbled. The CTS signal is obtained by a sum signal (A+B+C+D) of a photo detector 8. The CTS signal has a satisfactory amplitude. A push-pull signal is obtained by a difference signal (A+D)-(B+C) of photo detector 8. COPYRIGHT: (C)2004,JPO
