We fabricated disc-type multilayered media with several refractive indices of pressure-sensitive adhesives for dynamic layer detection. We modified a commercially available disc tester in order to obtain two types of signal; one is the confocal signal and the other is the astigmatic signal. The confocal signal provides sufficient signal to detect recording layers, but the astigmatic signal is not useful because the reflected signals from the internal layers are too small. The confocal detection also provides sufficient signal for rotating discs. We found that the intensities of the reflected signals of rotating multilayered media were of the same level as those of the fixed multilayered media. The reflections from the multilayered media can be used as focus-servo signals.
