A METHOD AND APPARATUS FOR READING INFORMATION STORED IN A FLUORESCENT MULTILAYER INFORMATION CARRIER

摘要

An apparatus and method for reproducing information stored in a fluorescent multilayer information carrier. The apparatus utilizes auto-focusing and auto-framing techniques when reading the information to enable parallel reading from uniformly moving carrier. To avoid discontinuity in motion, an actuator with an objective lens performs periodic motion following a specific moving information page and, after the end of reading of this page, returns back to follow the next page.
