THERMAL MANAGEMENT IN OPTICAL SCANNING APPARATUSES

摘要

An optical scanning apparatus for reading information from an optical disc, the apparatus comprising communication means for receiving instructions from and sending information to an internal or external host and decision means enabled to decide, when receiving a predetermined instruction for executing an associated action, to send information indicating successful execution of the associated action without executing the associated action. In particular, the predetermined instruction corresponds to a seek instruction, the optical scanning apparatus sending information indicating successful execution of the seek instruction without executing the seek instruction, if the measured temperature exceeds a threshold temperature.
