No. The RL01 and RL02 drives use embedded servo.

If the heads won't load, I would also suspect that the RPM isn't
detected within limits. I didn't know there was an active component
in the cartridge, but if it were missing or dislodged, that could
account for the symptoms.

I know more about the innards of the RK05, and it uses a cut aluminum
hub and a hall sensor to detect sectors - the cartridge is passive.
The gap in the hub rim triggers the hall sensor and a new sector
begins. I guess the RL01/RL02 must have a similar mechanism, but
with magnets, not gaps.
