Abstract
The present invention relates to a method for preventing a problem of collision between an optical system and a media by suggesting a method for confirming the kind of the medium prior to its operation in a drive having a compatibility with respect to a method for storing a near field optical information using SIL and a method for storing a remote field optical information below the existing blu-ray disk. The present invention can distinguish from an inserted optical disk if a compatible drive/pickup is in a near-field method, and confirm if the inserted optical disk is operable in a near-field method drive/pickup in advance, also.
Claims19
A method for confirming a recording media comprising:
- detecting a predetermined discriminating signal with at least one optical pickup of at least two optical pickups;
- determining if the predetermined recording media discriminating signal is redetected depending on if the discriminating signal is detected;
- and
- starting a recording/reproduction of data onto recording media using the corresponding optical pickup if the predetermined recording media discriminating signal is detected.
A method for confirming a recording media comprising:
- determining if a solid immersion lens (SIL) is placed on an optical pickup;
- detecting a predetermined discriminating signal on a recording medium depending on if the solid immersion lens is placed;
- determining if the predetermined recording media discriminating signal is redetected depending on if the discriminating signal is detected;
- and
- starting a recording/reproduction of data onto a recording media using the corresponding optical pickup if the predetermined recording media discriminating signal is detected.
