The RX02 format is specific to DEC and the RX02 and it can't be read or
written by anything other than an RX02 or something designed for that
task. The RX01 format is straight IBM 3470, but the RX02 has sector
header fields in FM and data fields in a modified MFM format. I have
never seen anybody claim it was even possible to read/write an RX02
using a PC disk controller.
This is from research I have done. I am sure somebody can supply more
details.
I don't have any RX02 drives, but I have built a little interface and
written some software that lets a PC running Linux or NetBSD act like an
RX02. I have used it with RT-11 on a PDP-11/40 and microPDP-11/73 and
with OS/8 V3D on a PDP-8/e.
