Try fast-forwarding through the tape with the 'mt' command.
Something like:
mt -f /dev/rmt0n fsf 1
Will fast-forward the tape by one set. Then you could try your tar command again when you get to the appropriate place in the tape.
Make sure you are using the "no-rewind" version of the tape device. See the mt man page for more info.

NAME
tcopy - copy a magnetic tape
SYNOPSIS
tcopy source [destination]
DESCRIPTION
The tcopy utility copies the magnetic tape mounted on the tape drive specified by the source argument. The only assumption made about the
contents of a tape is that there are two tape marks at the end.
When only a source drive is specified, tcopy scans the tape, and displays information about the sizes of records and tape files. If a des-
tination is specified, tcopy makes a copies the source tape onto the destination tape, with blocking preserved. As it copies, tcopy pro-
duces the same output as it does when only scanning a tape.
The tcopy utility requires the use of Berkeley-compatible device names. For example,
example% tcopy /dev/rmt/1b /dev/rmt/2b
