The RK05 was a moving head magnetic disk drive manufactured by DEC. [5][a] It stored approximately 2.5 MB on a 14", single-platter IBM-2315 -style front-loading removable disk cartridge. The cartridge permitted users to have relatively unlimited off-line storage and to have very fast access to such data.

The RK05 was moving-head magnetic storage disk drive, most versions of which used removable packs. They were designed and manufactured by DEC, and were based on, but not completely compatible with, the earlier RK02 and RK03 drives (which were sold by DEC, but not manufactured by them), which in turn were inspired by the IBM 2315 drive and pack.

2019年2月12日 · The RK05 cartridge for DEC (and the Diablo 31 for other minicomputer companies) became the preferred personal portable storage device. It enabled ‘load and go’ of different OSs on the PDP-11 and PDP-8, provided essentially unlimited offline data storage, and provided data interchange among compatible systems.

The controller for the RK05(f) is a dedicated backplane with 4 modules, called RK11 and is UNIBUS based. The RK11 can control up to 8 drives, but the RK05f appears as two logical drives with an even and an odd number, for example 2/3.

2021年7月27日 · DEC RK05 Notes . Apologies for the rough nature of this page. In it’s present state, this page just captures notes from my attempts to get some RK05 drives working on my PDP-11/34. Really Basic Stuff. Inside the RK05, check the lever switch is in the UP position; Under RT11, the RK05 shows up as RKn: (ie RK0:, RK1:, etc)

RK05 Drive Information. The RK05J Disk Drive is a removable media hard drive with a total capacity of 1.6 million 12 bit words. This was normally used with the PDP-8E type omnibus machines. It was attached to the computer with the RK8E 3 board set which transferred data using the omnibus data break.

2021年3月18日 · DEC had the RK05 exerciser but these are probably impossible to find. So I've drawn a PCB to interface with the disk. The test routines are described in the RK05 exerciser documentation. The idea is to put an Arduino Due on the board and plug it into the drive. Or use an Unibus cable and two H851 blocks. Then you could use the board outside the ...

Before Digital Equipment came up with the RK05 disk drive, they used a Diablo Model 30 drive, which was used by other minicomputer manufacturers as well. Those two – the RK03 and RK05 – are compatible and can interchange packs. Each pack stores about 2.4MB of information.
