One thing I can categoricly state is that that is not an amanda tape 
header.

It should resemble this for the above command line:
[root@coyote amanda]# od -c scratch1 | head
0000000   A   M   A   N   D   A   :       T   A   P   E   S   T   A   R
0000020   T       D   A   T   E       2   0   0   3   0   5   2   6
0000040   T   A   P   E       D   a   i   l   y   S   e   t   1   -   0
0000060   2  \n  \f  \n  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0
0000100  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0  \0
