Apparatus and method for enhancing playback fidelity of compact disks |
| abstract |
A method and apparatus improve the playback fidelity and quality of a compact disk player by controlling charge conditions in the zone of interaction between the playback read head and a CD. In one form of apparatus, an electrode is associated with the read head, and an ion generator coupled to the electrode provides an electrostatic field. The introduction of random noise to the field potentiates or enhances the improvement. |
