Patent ID: 7761887

Claim:
A recording medium for storing data comprising: first and second outer surfaces, the second outer surface adapted to be placed adjacent an optical pickup for transmitting a beam from the optical pickup to store data on, or read data from, the recording medium; a recording area; a clamping area; a center hole for receiving a spindle therein; a recording layer formed in the recording area between the first and second outer surfaces, wherein the recording layer is parallel with the first and the second outer surfaces and is closer to the second outer surface than to the first outer surface; and reflecting means, placed on the first outer surface, to prevent a beam from the optical pickup directed toward the first outer surface of the recording medium from traveling through the first outer surface of the recording layer and to enable the beam to be reflected to the optical pickup during a time that an objective lens in the optical pickup moves relative to the recording medium when the first outside surface of the recording medium is placed adjacent to the optical pickup, and wherein the width of the reflecting means is larger than the width of an area allocated for navigation data used in searching for data written in the recording layer along the radial direction of the recording medium.
