3M 300 XLP (PK5)

Description

45 MB Data Catridge.

The QIC cartridge is distinguished from other types of tape cartridges by containing an endless drive belt which is moved at a uniform speed by a motorised capstan.

Since the belt is in contact with the tape, this ensures both that the tape moves at uniform speed, and that neutral tension is maintained at all times.

This is in contrast to cassette tapes or DATs, where the tape is moved past the head by a capstan and pinch wheel, but the takeup reel is driven by a servo motor or slipping clutch.
