Disc detection device and associated method |
摘要 |
A disc drive apparatus is provided which determines a recording medium enabling type and recordability for various types of discs. The discs are housed in a cartridge and each cartridge has at least a first and second detection hole formed therein. The second detection hole (H 1 ) is variably opened and closed by an opening/closing device, and the first detection hole (H 0 ) is in an open state at all times. The disc drive apparatus determines the disc type using a light signal reflected from the loaded recording medium. The disc drive apparatus also determines disc determining parameters (for example, recordability of a disc) based on information received about the disc type and the open/closed state of one or more detection holes formed in the cartridge.
