METHODS FOR READING DATA FROM A STORAGE MEDIUM USING A READER AND STORAGE DEVICES

摘要

A system for reading data from a storage medium. The system includes a reader and a data determination circuit. The reader is configured to receive a first signal from a first position relative to the storage medium and read a second signal from a second position relative to the storage medium. Each of the first signal and the second signal includes a combination of first data stored in a first track and second data stored in a second track. The data determination circuit is configured to determine third data stored at a predetermined position using the combination of the first data stored in the first track and the second data stored in the second track as received in the first signal and the combination of the first data stored in the first track and the second data stored in the second track as received in the second signal.
