Cannot read 9-track tape

Question:

We have received an ASCII 9-track tape from the government that we 
cannot read.  We are only restoring every tenth record in the file.  
The tape has a density of 1600 and has a record size of 196, blocks 
of 10.  The dd command we are using is:

  dd if=/dev/rmt1.5 of=filename bs=196 fskip=1

We have the block size in SMIT set to 0 (variable).

Response:

Try using the following command:

dd if=/dev/rmt1.5 of=filename bs=1960 fskip=1

Since the tape has a record size of 196 and a block contains ten
records, you should set the block size (bs) for dd to 1960 rather 
than 196. 

Response:

We tried the above command and the datafile restored correctly.
