I think it recorded the directories at high (556) density, while the files themselves were at 200BPI for reliability. Just about as bizarre as it gets. Yeah, those were the days. I once destroyed the hub on a CDC drive by neglecting to tighten it down on the tape reel. Chunks of plastic were flying everywhere. -- Gregory R.
