A system and related methods for characterizing and improving optical drive read performance is presented. The system includes an innovative audio file stored on optical media (characterization file), and an optical drive characterization agent, implemented on a computing system. The optical drive characterization agent iteratively controls the optical drive to perform incremental reads of at least a subset of the characterization file, analyzes at least the subset of the characterization file read from the optical media, and generates one or more performance scores on an associated one or more performance attributes of the optical drive. In this regard, optical drive characterization agent quantifiably characterizes an optical drive's ability to accurately read individual sectors from optical media comprising audio content.
A system comprising:
A machine readable medium having stored thereon a plurality of executable instructions wherein at least a subset of which, when executed by a machine, implement an optical drive characterization agent to iteratively control one or more optical drive(s) to perform incremental reads of at least a subset of an audio file stored thereon, analyze the read subset of the audio file, and to generate one or more optical drive performance metrics based thereon.
A machine readable medium having stored thereon a plurality of information which, when read by an optical drive, enable a computing system coupled to the optical drive to quantifiably measure one or more performance attributes of the optical drive including read accuracy, wherein the plurality of information is an audio file comprised of a non-repeating audio pattern at least twice as large as a non-obvious offset for contiguous reads from the audio file.
