Semyon Korsakov was reputedly the first to propose punched cards in informatics for information store and search. Korsakov announced his new method and machines in September 1832. [8] Brown, Betsy (1987-12-06). "Westchester Bookcase". The New York Times. Edward Ziegler […] an editor at the Reader's Digest […] wrote a science fiction novel, The Man Whose Name Wouldn't Fit, under the pen name Theodore Tyler Punched cards, and chains of punched cards, were used for control of looms in the 18th century. Use for telegraphy systems started in 1842. Punched tapes were used throughout the 19th and for much of the 20th centuries for programmable looms, teleprinter communication, for input to computers of the 1950s and 1960s, and later as a storage medium for minicomputers and CNC machine tools. During the Second World War, high-speed punched tape systems using optical readout methods were used in code breaking systems. Punched tape was used to transmit data for manufacture of read-only memory chips.

Paper, as with any artistic material, can be a personal choice, and there are a few different options. I will break down some items to consider when choosing animation paper, as well as sharing what I prefer to use myself and my reasons why. For heavy-duty or repetitive use, polyester Mylar tape was often used. This tough, durable plastic film was usually thinner than paper tapes, but could still be used in many devices originally designed for paper media. The plastic tape was sometimes transparent, but usually was aluminized to make it opaque enough for use in high-speed optical readers. The Univac UNITYPER introduced magnetic tape for data entry in the 1950s. During the 1960s, the punched card was gradually replaced as the primary means for data storage by magnetic tape, as better, more capable computers became available. Mohawk Data Sciences introduced a magnetic tape encoder in 1965, a system marketed as a keypunch replacement which was somewhat successful. Punched cards were still commonly used for entering both data and computer programs until the mid-1980s when the combination of lower cost magnetic disk storage, and affordable interactive terminals on less expensive minicomputers made punched cards obsolete for these roles as well. [31] :151 However, their influence lives on through many standard conventions and file formats. The terminals that replaced the punched cards, the IBM 3270 for example, displayed 80 columns of text in text mode, for compatibility with existing software. Some programs still operate on the convention of 80 text columns, although fewer and fewer do as newer systems employ graphical user interfaces with variable-width type fonts.

If you are aiming for performance oriented animation, or more sophisticated feature film animation in the Disney tradition, you will need the canvas size that 16 field offers you. This will become obvious to you as you progress. When starting out with basic exercises, 12 field is enough. However as you progress, you may feel restricted and that you need more space to draw. 12 field will eventually become quite limited, especially when handling acting, lip sync, and complex performance. In the 21st century, use of punched tape would be very rare, possibly in obsolete military systems or by some hobbyists. In computer numerical control (CNC) machining applications, paper tape is uncommon, but some modern systems still measure the size of stored CNC programs in feet or meters, corresponding to the equivalent length if the data were actually punched on paper tape. [3] Formats [ edit ] Diagnostic minicomputer software on fanfold paper tape (1975) Mylar punched tape was used for durability in industrial applications In 1956 [30] IBM signed a consent decree requiring, amongst other things, that IBM would by 1962 have no more than one-half of the punched card manufacturing capacity in the United States. Tom Watson Jr.'s decision to sign this decree, where IBM saw the punched card provisions as the most significant point, completed the transfer of power to him from Thomas Watson, Sr. [21]

At the University of Wisconsin – Madison, the exterior windows of the Engineering Research Building [80] were modeled after a punched card layout, during its construction in 1966.
