Umm if you store binary ... that is 80 bytes per card .. 46 feet per file.
Now how many dec tapes is that?
Didn't someone once work out that to store a
single MP3 you'd need a
stack of 80-column cards ten miles high?
Assuming a 6MB MP3 file and 40 bytes per card:
6 * 1048576 = 6291456 bytes
/ 40 bytes per card = 157286.4 (157285) cards
* .178mm card thickness = 27996.73 mm high
/ 25.4mm per inch = 1102.233465 inches
/ 12 = 91.85278871 (91.85) feet
