ABSTRACT:
A hybrid disk useable with a recording and or reproducible apparatus having an optical pickup. The hybrid disk includes a first recording layer having a first format on which data is recordable or readable by a first format beam and a second recording layer having a second format on which the data is recordable or readable by a second format beam. The transmivities and reflectivities of the first and second recording layers are interrelated to control relative intensities of the first and second format beams incident on the optical pickup.
