A nano data writing and reading apparatus using a cantilever structure includes a cantilever formed by patterning a deposition material deposited on a sacrificial substrate, a probe formed at a front end portion of one surface of the cantilever and formed simultaneously with the cantilever as the deposition material is filled in a probe groove pattern formed on the sacrificial substrate when the deposition material is deposited on the sacrificial substrate, a heater formed of polycrystalline silicon at the cantilever, for heating the probe, a data sensing unit formed at the cantilever and sensing data written on media, a signal connection pad connected to the data sensing unit and formed at the cantilever to provide an electrical connection with an external signal line, a signal transfer circuit unit connected to the signal connection pad, for controlling writing and reading of data on and from the media, and a bonding unit allowing the cantilever to be supported at the signal transfer circuit unit and providing a passage for an electrical connection between the signal connection pad and the signal transfer circuit unit. Accordingly, the cantilever and the probe can be precisely formed by a molding technique through the removal of a sacrificial substrate and are formed of a deposition material such as a silicon nitride material, thereby remarkably reducing variations in a thickness of the cantilever and improving the durability of the probe. Also, because a bonding process with a glass wafer for fabricating the cantilever structure is not required, the process is facilitated and a fabrication coast is greatly reduced.

An optical pickup apparatus is capable of recording data in and/or reproducing data from recording mediums with different formats by using one single optical system. The optical pickup apparatus includes an optical system, wherein a filtering surface that transmits or reflects wavelengths from different rays coats the peripheral portion of the center portion of an input surface and the peripheral portion of the center of an output surface. A transmitting surface having a conical shape is disposed in a central portion of the input surface and projected inwardly or outwardly with respect to the input surface. Therefore, the optical pickup apparatus can be applied to different recording mediums using rays having different wavelengths and a lightweight, small optical pickup apparatus can be implemented by using one single optical system.
