TM (IV) 6/12/72 TM (IV) NAME tm -- TM-11/TU-10 magtape interface DESCRIPTION mt? is the DEC TU10/TM11 magtape. When opened for reading or writing, the magtape is rewound. A tape consists of a series of 512 byte records terminated by an end-of-file. Reading less than 512 bytes causes the rest of a record to be ig- nored. Writing less than a record causes null padding to 512 bytes. When the magtape is closed after writing, an end-of-file is written. Seek has no effect on the magtape. The magtape can only be opened once at any instant. FILES /dev/mt0 selected drive 0 SEE ALSO mt(I) BUGS Seek should work on the magtape. Also, a provi- sion of having the tape open for reading and writing should exist. A multi-file and multi- reel facility should be incorporated.
