No, RX01 (and RX02) are soft-sectored.

Soft-sectored disks have one index hole punched near the centre, and an
optical sensor detects this once per revolution, indicating the logical
start-of-track. Hard-sectored disks have one hole per sector, and the
sensor detects these to indicate start-of-sector; the first sector is
distinguished because there's an extra hole (the index hole) punched
halfway between two sector holes.
