A method of writing on a two-reel, belt driven, multitrack tape cartridge wherein tape tension increases with the progress of tape transportation from one reel to another. Forward tracks on the tape are predivided into a first group adjacent the tape centerline and a second group adjacent one tape edge, and reverse tracks are similarly predivided into a first and a second group. Writing on each of the first group of forward tracks is started in a position spaced a less distance from the tape beginning than on each of the second group of forward tracks. Writing on each of the first group of reverse tracks is also started in a position spaced a less distance from the tape end than on each of the second group of reverse tracks. Thus the tape offers a greater storage capacity than if, as is conventional in the art, writing on the first groups of forward and reverse tracks is started in the same longitudinal tape position as on the second groups of forward and reverse tracks.
