1/4" tape and record sizes

[Benson I. Margulies]

My 320 has the usual IBM/tandberg 1/4 inch polymorphously perverse
tape drive. (anyone know where to get a drive like this that writes
both 60 and 150 MB for a sun?)

In smit, its configured for 512 byte blocks. I write tapes with backup
-i (for consumption of installp). tcopy, documented to report on
record sizes, swears that the tape blocks are 65536 bytes long.
I think it's lying. Can anyone convince me otherwise?
