	The RS-11 is a fixed-platter fixed-head disk drive ~~that can~~ store up to 524KB of data, addressable on 16 bit word boundaries (most other DEC disk drives of this era ~~had~~ 512 byte blocks). The drive used 128 fixed read/write ~~heads~~ and recorded data on a single nickel-cobalt plated surface. ~~The~~ data ~~transfer rate~~ was ~~125K bytes per second~~.		The RS-11 is a fixed-platter [[fixed-head disk]] [[drive]] which could store up to 524KB of data, addressable on 16 bit [[word]] boundaries (most other DEC disk drives of this era used 512 byte blocks). The drive used 128 fixed read/write [[head]]s, and recorded data on a single nickel-cobalt plated surface.

			It provided one [[parity]] bit per word; data words are stored in a 22-bit format, with guard bits (2 at the start, and 2 at the end) and a [[sync]] bit. A spare set of 3 timing tracks, recorded in [[phase]] with the primaries, provided redundancy for the 3 primaries..

			It was packaged for rack mounting in a standard 19 inch rack, such as an [[H960 rack\|H960]]. Its controller was the [[RF11 disk controller]] (also rack mounted).
