    I've occasionally used 'tapedd' to image magtapes.  It's part of the 
klh10 emulator:


Usage: tapedd <params>
   itX=<path>	(Required) Input Tape device, where 'X' is optional
 		drive spec: (defaults to 'h')
 		     h - Half-inch magtape drive (default)
 		     q - QIC (quarter-inch cartridge) drive
 		     8 - 8mm drive
 		     4 - 4mm DAT drive
 		    vF - Virtual tape & drive, where 'F' is optional
 			format spec: (defaults based on file extension)
 			   r - Raw format, paired with control file
 			   s - TPS format
 			   e - TPE format
 			   c - TPC format
   otX=<path>	(Required) Output Tape device, X as above
   {i,o}c=<path>	alternate tape Control file (old id=,od=)
   {i,o}f=<path>	alternate raw data file
   {i,o,}bs=<n>	Block size (record length)
   log=<path> 	Log filespec (defaults to stderr)
   rskip=<#>	Skip # input records
   fskip=<#>	Skip # input files/tapemarks
   rcnt=<#>	Max # records to write
   fcnt=<#>	Max # files/tapemarks to write
   peot		Use physical EOT, ignore logical EOT (double tapemark)
   test		Parse control file, output result to stdout
   verbose	Verbose
