Abstract
Base plates for magnetic data tape cartridges, are initially formed from roll stock of sheet material and are processed to form apertures to receive press-fitting tape guides and pins. The base plates are stacked in orientations that inhibit alignment of apertures, and the stack of base plates is heated at elevated temperature for a substantial time interval while simultaneously being pressed between plane parallel dies to relieve internal stresses and assure planarity within close tolerance limits of the base plates and the regions around the apertures.
