Mystery disk cleaner

[Qbus]

Anybody have any idea what type disk pack this cleans? A RK or RL? And what they used for fluid?

I am not an expert, but it probably is not an RK because I believe that RK disk packs have 2 platters. This looks like it only has facilities for one platter.

If you zoom in on the photo of the serial number plate it looks like the OPTION tag is RL01K-AA

Yes, that is for RL packs. RK packs would need some extra hardware to lift up the door to access the disk. Interesting looking device, but I don't know if I would trust any of my packs to it. It looks like the foam on the "head" arms is shot.

Do all RK disk packs have the door on them? My disk packs are RK07 packs, and they do not have the door, but a window directly to the platters.

Having a disk cleaner would be very handy. My disk packs were stored in a very dusty place before I obtained them, and I am afraid to use them and ruin the disk and possibly the read/write heads.

Sorry, I should have been more specific. RK05 and earlier have the doors (the single platter packs).

Ah okay. The only RK disk packs that I have seen are the RK07. I have some RL02 disk packs, but no drives for them.

I've cleaned many an RK05 manually. I am not sure how you'd do that with a multi-platter disk.

Okay. I don't want to take over this thread, but when I finally get my PDP-11/44 operational I will probably start a new one. It would be very cool to use the actual disks instead of using the ethernet boot.

So did anyone here win it?
