ABSTRACT:
An optical pick-up apparatus including an optical source module having a CD optical source and a DVD optical source, a diffracting grating dividing a light beam from the optical source module to at least three divided light beams, a first optical divider changing a path of the divided light beams to an optical disk, a second optical divider reflecting and forwarding the divided light beams reflected from the optical disk in a predetermined ratio, a first optical detector including a single optical sensor receiving reflected light from the second optical divider, and a second optical detector including at least three optical detection sensors receiving forwarded light from the second optical divider. Embodiments of the present invention can provide support for multi-type optical disks with a simple optical structure.
