Recording characteristics of guided-layer media consisting of planar recording layer and land/groove patterned guided-layer were investigated. Guided-media can be operated with a focusing servo and a tracking servo on the planar recording layer and the guided-layer, respectively. Recording properties using not only two blue lasers but also one blue and one red laser were measured. The jitter of about 8% was obtained from the planar recording layer on the guided-layer using two blue lasers system. Even though the jitter was not obtained, a similar performance to the previous result was observed with the blue laser and the red laser system. Though these experimental results, the possibility of high recording density with increasing data transfer rate could be confirmed.
