In addition, the OLEDs can be fabricated onto a flexible plastic substrate rather than a rigid glass layer, making it easier to manufacture them into a curved screen.

However with the introduction of lighter weight and more flexible plastic substrate magnetic tapes, combined with a vacuum column to control the tension that the magnetic tape experiences during use, the IBM 726 was a prototype of the modern digital tape recording system.
