Limitations
The three biggest problems with paper tape were:
- Reliability. It was common practice to follow each mechanical copying of a tape with a manual hole by hole comparison.
- Rewinding the tape was difficult and prone to problems. Great care was needed to avoid tearing the tape. Some systems used fanfold paper tape rather than rolled paper tape. In these systems, no rewinding was necessary nor were any fancy supply reel, takeup reel, or tension arm mechanisms required; the tape merely fed from the supply tank through the reader to the takeup tank, refolding itself back into exactly the same form as when it was fed into the reader.
- Low information density. Datasets much larger than a few dozen kilobytes are impractical to handle in paper tape format.

Famous quotes containing the word limitations:
“The limitations of pleasure cannot be overcome by more pleasure.”
—Mason Cooley (b. 1927)
“No man could bring himself to reveal his true character, and, above all, his true limitations as a citizen and a Christian, his true meannesses, his true imbecilities, to his friends, or even to his wife. Honest autobiography is therefore a contradiction in terms: the moment a man considers himself, even in petto, he tries to gild and fresco himself.”
—H.L. (Henry Lewis)
“Growing up means letting go of the dearest megalomaniacal dreams of our childhood. Growing up means knowing they can’t be fulfilled. Growing up means gaining the wisdom and skills to get what we want within the limitations imposed by reality—a reality which consists of diminished powers, restricted freedoms and, with the people we love, imperfect connections.”
—Judith Viorst (20th century)
