摘要： An optical pickup device includes a light unit for irradiating a light beam having a wavelength longer than 650 nm onto a recording medium and receiving and detecting a light beam reflected by the recording medium, and an objective tens formed of a single lens having an NA of 0.7 or more to form a light spot on the recording medium by condensing an incident light beam emitted from the light unit. A recording medium has a recording density of a DVD family or more and is formed of a material suitable for a long wavelength of 700 nm or more so that a reproduction signal by a reflectance of a recording surface is optimized. Thus, a compact high density optical recording/reproducing apparatus which is inexpensive and has high performance can be realized.

摘要： An optical pickup including a many-sided reflection prism formed as a single body with a plurality of reflection faces to guide a light beam incident through a transmission face in a horizontal direction perpendicular to a height direction by reducing a size of the light beam in the height direction, by using a difference in angles between the reflection faces, and to reflect the guided light beam in the height direction by one reflection face of an angle less than 45° with respect to the horizontal direction. By using the many-sided reflection prism, the height of an optical system can be reduced regardless of the wavelength used without reducing light beam size. Thereby, slim-sized optical pickups can be implemented.
