Abstract:
A method and structure for intensifying track seeking signals from an optical disk, in particular, a recordable digital versatile disk (DVD-R). With the addition of an optical correction layer between a dye material layer and a reflection layer inside the DVD-R, track-seeking signals of the optical disk are intensified and recording quality of the optical disk is improved. The optical correction layer is a transparent or semi-transparent layer made from inorganic materials. The optical correction layer is formed over the dye material layer in a sputtering process.
