Aucbvax.4882 fa.unix-wizards utzoo!decvax!ucbvax!unix-wizards Sun Nov 1 19:59:57 1981 Tape records and the 2048 byte limit >From decvax!duke!bcw@Berkeley Sun Nov 1 19:49:47 1981 The 2048 byte limit was originally the limit on some ancient tape drive of the IBM 704 series vintage (I don't remember offhand which one or even if it was an IBM drive). It got written into the ANSI standard tape format as a file inter- change (not hardware) limit; many installations allow the creation of larger records with the caveat that the result may not conform to the ANSI standard and therefore may not be readable on more restrictive sites.

Most modern hardware allows 32-64KB per tape block.
