Utterly fascinating stuff, thank you.
(Aside: for some time I wondered about the efficiency effects of reading whole tracks into the on-disk memory; then it occurred to me that of course there is no efficiency reduction. That data is passing under the head *anyway*, and the disk has to read it in order to find the correct sector, and reading it doesn't cost anything; so why not cache it to assist future requests?)
