I have here a book entitled "IBM 360 Assembler Language Programming", published by Wiley in 1970. On page 409, at the beginning of the chapter entitled "Direct Access Storage Devices (DASD)", I read DASDs available for System 360 are listed below. 1. Drive with removable disk packs: 2311 and 2314. 2. Drive with non-removable disk packs: 2302. 3. Drum: 2301 and 2303. 4. Data Cell drive: 2321. There's very little mention of the word disk in the chapter (and none of the alternative "disc"). I don't think that the term was new at the time the book was written.
