Abstract
The application of heterostructure lasers to video disk systems is described. The buried heterostructure diode laser is used as a light source of the optical pickup for the optical video disks. This pickup enables video signals to be reproduced with a SNR of more than 40 dB. These lasers can be not only used as a light source to read out the signal from the disk but also as a detector of the reflected light.Keywords
