Title (EN) SYSTEM AND METHOD FOR READING A MAGNETIC TAPE
(
Abstract: (EN)A system for reading a magnetic tape is provided. The system comprises a magnetoresistive head, a tape controller, an analog-to-digital converter and a processing unit. The tape transport controller controls a movement of a magnetic tape with respect to the magnetoresistive head. The analog-to-digital converter generates a signal upon receiving an analog signal read by the magnetoresistive head on the magnetic tape. The processing unit identifies a magnetic flux transition in the signal to detect a bit from the signal from the signal based on the identified magnetic flux transition. Identification of the magnetic flux transition in the signal includes analyzing voltage wave forms of the signal. A method and a computer readable storage medium for reading a magnetic tape are also disclosed.
