Abstract
An optical disc includes an annular substrate, a coating layer, and a compensation sheet. The annular substrate has a supporting portion, a recording portion surrounding the supporting portion, and a recording surface corresponding to the recording portion. The coating layer is formed on the recording surface for recording data. The compensation sheet is attached to the annular substrate so that the coating layer is sandwiched between the annular substrate and the compensation sheet, and that the thickness of the optical disc at the recording portion is the same as the thickness of the optical disc at the supporting portion, wherein the data read/write is performed from the compensation sheet side of the optical disc by a driving device. A method of fabricating the same is also disclosed.
