8-sector decpacks?

[Josh Dersch]

Does anyone have any idea what drive/system an 8-sector decpack would have been used with?  We have a few of them on our shelves at the LCM and I can't find any reference that mentions 8-sector packs.  (Just the usual 12 and 16-sector ones.)

They're clearly labeled "decpack 1100 BPI - 8" and the sector ring marks out eight sectors.  These are RK05 (IBM 2315) style packs.

Thanks,
Josh
