Abstract
A disc structure for making an inverted optical response through a super-resolution process using a recorded mark portion and a space portion, which is realized to amplify a signal amplitude and solve a conventional problem that a conventional super-resolution technique can obtain only small signals, since the super-resolution area is reduced to realize high density recording of data.
