ABSTRACT:
Disclosed is a magnetic tape transport system which has multiple magnetic heads arranged parallel to each other that a magnetic tape slides in contact with, and which has a structure to prevent a decrease in contact pressure between the magnetic tape and the magnetic heads. The magnetic tape transport system includes a supply reel for feeding the magnetic tape, a take-up reel for winding the magnetic tape fed from the supply reel, a plurality of magnetic heads being arranged parallel to each other, a partition plate for dividing a space between the magnetic heads into an air space and a close-tape space, a negative pressure generation means for setting a pressure in the air space to be lower than that in the close-tape space, and a communicating path for allowing the air space and the close-tape space to communicate with each other.
