System and method for correcting interference errors in data encoded on storage media

A system for correcting interference errors in data encoded on a storage medium, said storage medium including tracks, said system comprising:

• position marks disposed on a surface of said storage medium, said position marks being configured to encode addresses of said tracks and to encode track types;
• a head device for directing a light beam towards said position marks to produce a reflection of said light beam;
• and
• a correction module configured to combine each of said addresses with one of said track types to detect and correct errors in said addresses, and further configured to evaluate said reflection to calculate a position error signal for position correction of said head device.

A computer-readable medium comprising program instructions for correcting interference errors in data encoded on a storage medium having tracks by performing the steps of:

• sensing a reflection of a light beam from a head device directed towards position marks disposed on said storage medium;
• using said reflection of said light beam to read addresses of said tracks and track types using a correction module;
• combining each of said address of said tracks with one of said track types to detect and correct errors in said addresses using said correction module;
• and
• using said reflection of said light beam to generate a position error signal for position correction of said head device using said correction module.
