Sony's R50 dodges SCMSAll you need is a 24K resistor.
Follow these steps to make a digital copy of a digital copy with your R50:
- Connect the TOSLink optical cable to the optical in on the MZ-R50 and the
optical out of your digital source.
- Slide the REC lever or push PLAY (Display should flash NO
COPY if you pressed record and the source is playing)
- Momentarily connect a 24K resistor to pins 2 and 4 (counting from left to
right on the remote jack). (photo)
A 24K resistor can be found at RadioShack for a fraction of a dollar. It can
be bent into a U shape and inserted into the remote socket. There is little
risk of shorting out the pins, but try to contact only the second and fourth
pins. While inserting the resistor, watch the display. A very brief blip in
the text area of the display will indicate that you have made the appropriate
connection, and can then put the resistor away and continue with the next
- Slide HOLD switch to hold (yellow dot now visible).
- Push |<< or >>| repeatedly to scroll through the
parameters tabled below to SCMS ON
- Pushing PLAY Toggles SCMS ON to SCMS OFF. At this
point, the recorder is still in record pause if you hit RECORD, or is
playing if you pressed PLAY in step two.
- Now slide the HOLD switch back to the normal position to record
without SCMS. SCMS OFF must be on display during this step.
ROM version 1.40 and later:
If you have ROM version 01.40 or later, you may be out of luck. Sometime
in February/March, Sony corrected this hole in a new ROM version. You can
check the ROM version by inserting the resistor while the unit is off. Be very
careful, as this puts you in Test Mode, where you can cause maladjustment of
settings that may cause your R50 to not operate properly. Once you have
checked your ROM version, remove all power to exit test mode.Permanent
See this other page
about soldering the 24k resistor inside the back cover. This does away
with carrying around and fiddling with the silly resistor.
- The recorder is now in a new mode of operation, and will remain so until
you remove all of the three power sources (Alkaline pack, Li-Ion pack, wall
adapter), not including the internal clock battery. The only operational
difference with this mode is that the hold switch has a new function: to
switch into (or out of) 'parameter' mode, where you can change SCMS setting,
- SCMS OFF will remain until all power is removed or you re-enter
test mode (with hold switch) and toggle it back to SCMS ON. After
cycling the power source, the unit operates normally, in all respects.
- This is not the true test mode for this model. The real test mode contains
some five categories (Servo, Audio, Mecha, Power, General Adjustment)
and can be accessed by completing step 3 above when the recorder is
off, then pressing PLAY. Do be careful in the real test mode, as some
setting changes will render your unit inoperational.
- Apparently, this scms-off feature writes copyprotection bits 10 to the
disc, so you cannot make digital copies of this track the way you can with the
stripper. Copyprotection bits set to 11 allows one generation copy, and is
what consumer decks write to tracks recorded from an analog source. SCMS
strippers actually convert bits 11 and 10 to 00, which allows unlimited
digital copying, so they only need to be used once per tree.
- If the recorder is stopped and in parameter mode, pressing the
Title/Enter button raises/lowers the record head and unlocks/locks the
- It is not yet known whether this will work on the R30. Actually, four
owners have reported it to not work. If it works for you, please notify
- Those of you familiar with the old nintendo shortcuts will appreciate this
resistor-less method of entering test mode on the R30's and R50's. While
holding down the PLAY button, press the following buttons in sequence*:
You should now be in Test Mode. Note the
difference between test mode where you can (mis)calibrate your unit, and what
I call parameter mode, where you disable SCMS. To date, I've had about five
readers ask about undoing their fiddlement in test mode (they broke their
units). Be careful.
