Byte 03, Bits 7 through 5 - RTF (Read Tape Format)
These bits are ignored by the CTS in the MODE SELECT command.
They are returned by the MODE SENSE command to indicate the
format of the data on the currently loaded data cartridge, as follows:
000b – The data on the tape is in 8500 format (EXB-8505)
001b – The data on the tape is in 8200 format
010b – The data on the tape is in 8500c format (EXB-8505)
011b – The data on the tape is in 8200c format
The value returned by the RTF field indicates the format that the CTS
willusewhenitreadsthetape.
Note: If the tape is blank or written in an unrecognized format or if
the CTS is not ready, the CTS returns the format in which it
would write if the tape were positioned at LBOT (that is, the
currently selected write density).
Byte 03, Bits 4 through 2 - WTF (Write Tape Format)
These bits are ignored by the CTS in the MODE SELECT command.
They are returned by the MODE SENSE command to indicate the
format that will be used when the CTS writes data to the tape, as
follows:
000b – 8500 format (EXB-8505)
001b – 8200 format
010b – 8500c format (EXB-8505)
011b – 8200c format
The value returned for these bits reflects the default density, the
density set with the most recent MODE SELECT command, or the
density of the data already on the tape.
