Helical-Scan Recording
To increase the amount of data that can be recorded on the tape, the tape drive implements advanced
The combination of the helical wrap of the tape around the drum, the rotation of the head/drum assembly, and the linear motion of the tape causes the heads to trace a track across the tape that is 2.47 inches (62.7 millimeters) long, at an acute angle of approximately 5 degrees to the bottom edge of the tape.
