Thank you.
When sending the following command to a MZ-RH1:

USB: Query to send: 00
USB: Query to send: 18
USB: Query to send: 06
USB: Query to send: 02
USB: Query to send: 20
USB: Query to send: 10
USB: Query to send: 01
USB: Query to send: 00
USB: Query to send: 00
USB: Query to send: 30
USB: Query to send: 00
USB: Query to send: 04
USB: Query to send: 00
USB: Query to send: ff
USB: Query to send: 00
USB: Query to send: 00
USB: Query to send: 00
USB: Query to send: 00
USB: Query to send: 00

I receive a 08 NOT_IMPLEMENTED in reply. Assuming the above command is
correct - is it perhaps the case that "content_creation_date_and_time"
cannot be retrieved using a MZ-RH1? The track tested is a SP track - the
"content_creation_date_and_time" shows up in the display of the player, so
it is there.
