NAME
rk - RK-11/RK03 (or RK05) disk
DESCRIPTION
Rk? refers to an entire RK03 disk as a single
sequentially-addressed file. Its 256-word blocks are
numbered 0 to 4871.
Drive numbers (minor devices) of eight and greater are
treated specially. Drive 8+x is the x+1 way interleaving of
devices rk0 to rkx. Thus blocks on rk10 are distributed
alternately among rk0, rk1, and rk2.
FILES
/dev/rk?
BUGS
Care should be taken in using the interleaved files. First,
the same drive should not be accessed simultaneously using
the ordinary name and as part of an interleaved file,
because the same physical blocks have in effect two
different names; this fools the system's buffering strategy.
Second, the combined files cannot be used for swapping.
