Patent ID: 6914860

Claim:
A method of detecting a reproducing signal using an optical detection device to receive an optical signal reflected from a single track on an optical recording medium and dividing the received signal into multiple signals corresponding to sections of the optical detection device which are arranged in a matrix with rows in a tangential direction and columns in a radial direction of the optical recording medium, comprising: selecting signals which are less degraded than other signals, from among the multiple signals corresponding to sections of the optical detection device, on the basis of data conditions recorded on the optical recording medium, interference between optical signals reflected/diffracted from pits in close proximity to each other and from adjacent tracks on the optical recording medium, and/or various system states; and obtaining a reproducing signal from the selected signals by compensating for an amount of the interference caused by the data conditions, the interference between optical signals reflected/diffracted from pits in close proximity to each other and from adjacent tracks on the recording medium, and/or various system states.
