In all tape widths including ¼", some studio machines use one-sided platters instead of reels. As normal studio practice is not to rewind immediately after recording or playing but rather to store tape with the start end in to take advantage of the even tension produced by the tape transport, tapes from these machines were generally stored on the platters even if the machine was capable of mounting an NAB reel. Other machines used NAB or custom reels in the larger width.
