Indeed, it's true. I'd even trade two-for-one to get some 16-sector packs.
Would it be worth the experiment to butcher a 12-sector pack into a 12-sector
pack and reformat it? 12 sectors = 30 degrees, 16 sectors = 22.5 degrees.
The idea would be to patch over eight of the slits on the 12 sector pack and
cut 12 new ones (by bisecting the circle several times).
I haven't disassembled an RK05 in years (the last time was in 1988 when my
boss pointed me at two pallets of drives and asked me to get two working
units out of the pile - I got four working and carted home the scrap) - the
sensor that detects the slits in the pack is optical, not hall-effect, right?
Just a thought.
