Abstract
A method and apparatus for reading a storage medium is provided. The apparatus includes a plurality of emitters configured to emit a radiant energy at a predetermined optical wavelength, a plurality of detectors configured to detect the radiant energy at the predetermined optical wavelength, and a storage medium holder configured to hold the storage medium between the plurality of emitters and the plurality of detectors. A first detector is configured to detect radiant energy which is emitted by a first emitter through data holes of a first track of the storage medium, and a second detector is configured to detect radiant energy which is emitted by a second emitter through data holes of a second track of the storage medium.
