Abstract
A tape drive system for ensuring tape data integrity by tape surface inspection, the tape drive system being configured for reading and writing data from/to a magnetic tape, is provided. The tape drive system includes a laser inspection unit comprising a sender and a receiver integrated into the tape drive system, wherein the laser inspection unit configured for recognizing a tape defect by scanning the magnetic tape when the tape drive system is in operation. The tape drive system includes a read/write head configured for acting together with the laser inspection unit as sensors for providing sensor data during a read/write operation of the tape drive system, a communication link between the sensors and a controller unit for exchanging sensor data. The controller is configured for evaluating sensor data and for triggering predefined actions based on the respective evaluation results such that the tape data integrity is ensured.
