"DEC came out with the 125 TPI RL01 disk drive in 1978,which was the first

Sounds to me like it was different, but in a good way?

A good way, definitely. Embedded servo enables the vastly higher densities we have today,
and also enables the use of all surfaces. A dedicated servo surface is not a major hit on
an RP06 that has 10 platters, but on a one or two platter pack it's way too much
overhead.
