I looked at the picture more closely in the link I supplied earlier and the storage facility clearly has more than one platter (looks like six to me, but ICBW [1]). Then it qualifies for Skorupka's definition of disk as it is chopped up. Or maybe it is really six drums all on one spindle? :-) Ok. It was a disk. By the way, Shmuel's "ObAbrahamLincoln" reference, for those who didn't catch it, was this: “Four… The fact that you call a tail a leg doesn’t make it a leg.” [when Lincoln was asked how many legs a dog has if you count its tail as a leg] >We had one for the MVT Jobque and when we went MVS we put PLPA on it. >We had one user that for 1 week a month was allowed to put a heavily >used dataset on it.

But I would have tried harder for a code change: move 3-5 records into a GETMAINed area. When you need the records again, move them to wherever from the GETMAINed area. No I/O at all to any external storage device for these 3-5 records. Of course I don't understand what else this program was doing, so ICBW.
