What's the latest RLL

The last info I read from a tech. book was RLL 2,7 and RLL 3,9 is not commonly used. That info was in 1996 and now 2002, is there any changes or what's the latest RLL in used for Hdd ?

RLL = Run Length Limited.

AFAIK RLL is no longer used. Like MFM. Too slow. Too small.
Read up on SCSI, now that is more fun!

I bought into EISA when it was finally about to get knocked out of the game.

One thing I lost track of, for RLL, was that there were some niche areas where they'd make a teeny one and stick it on a card that you could put into a slot. At one time they were going to address RAM on a card as if RLL (Ram for speed, RLL for compatibility). I can only assume that these tacks also fell into 'history', but there are so-o many 'toys', I really dunno. If CD didn't knock it off the stack, likely DVD did. (We can only have just so many mass storage devices massively produced, in quantity - for economy)

Thanx, and
Good Fortune!
