- Another Look at a Professional Disc Video Camera. This time a Sony PDW-530. We try it out then take it apart to see what is inside.

I have never seen this type of disc recording medium before I found your videos! So interesting, thanks for your efford!
Yea, Me too until I got this stuff. Quite unknown outside of professional equipment from a specific time period.
23:45 From the manual it looks like a WRR-855A/855B wireless receiver for WL-800 series wireless microphone transmitters could plug into that module slot. Also, a CBK-PC01 Memory Card Adaptor, or a CBK-NC01 Ethernet (100Base-TX) Adaptor could plug into that module slot.
37:35 The NEC uPD30131 is a VR4131 64/32-BIT MIPS RISC architecture microprocessor.
Thanks for the info.
I should have realized it is for a radio mic receiver, I have some in that form factor! Although on mine the aerial also goes out that back so I don't think it would work in this camera.
On Russky Avito I bought a Sony dsr 400p for $10 and a lens for $30. The camera is in excellent condition, but the lens had to be disassembled and the lenses cleaned. I'm filming with her now
Good find for a nice price.
Another cool vid that I only had time for to watch today haha. Thanks! The mystery component at 20:58 or so is RX-8025NB, which is an RTC from Epson/Seiko, with a built-in crystal. It's a current/active part. As another point to note, Sony has their ">EP GW
Interesting note about the >EP GW< thing. I've noticed that on a lot of boards. You don't see the UL mark so much. It's there on some, small and out of the way.
I only know how to use Altium, since I have always used it, and before that Protel99 which works more or less the same.
I was aiming to cover the techniques and important things more than it being a 'how to use the software' thing.
tearing down disc drive optical sleds always make me feel like im breaking art lol they are just so pretty and cool looking. also at 50:22 ish those colored glass thingys are probably dichroic glass, to reflect some wavelengths and let others pass and that def is a long optical sled. i tear down disc drives for the laser diodes to make pointers with them, out of like 50ish i havent seen one that long yet. interesting stuff. would totally watch you tearing down specifically disc drives. OH and yea ive seen little motors that move a lens in the sleds themselves. thats probably happening there too.
Can you get a useful laser out of it? This one would be blue.
How do you drive it?
@@Elecami you could make a laser pointer out of it, or maybe sell the diode. though id advise against trying to power it on unless you have laser goggles from a trusted source.
from what i found in datasheets for similar disc drives is that one you have most likely has a 35mw continuous (65mw pulse) 405nm purple laser diode in it (always assume its more if you dont know 100% for sure what it is...always assume its more dangerous than you think and remember you cant fix eyes, accidents happen at the speed of light with this stuff so safety first as always!) anything above 5mw is an eye hazard, that diode can burn things of course. so again dont power it on unless you have goggles (not sunglasses or a welding mask but proper laser goggles for the correct wavelength and power).
i have stayed behind my phone in the past to take cursed beam shots but its extremely sketchy (dont do that). if your VR has some passthrough cams that might work out ok though, for a short power on to make a video but you lose depth perception of course if its not stereo. just make sure you have a way to cut power instantly if you do the vr thing.
if you end up getting goggles or something, you can drive it with a CC source like an LED or laser diode driver, LM317 ect, something constant current. (or if youre really good figure out the driver already attached and use it) and beware of powering laser diodes with bench PSUs, they have a spike when it first powers on that has killed so many of my diodes...they are extremely fragile constant current devices and ESD from you touching them can kill them. also that spike is dangerous in other ways because the diode outputs way more for a moment if it survives.
anyways ya the one you have there would probably lase at 25ish ma with a typical operating current of 50ma at 4.9v.
@@naomi10260 Thanks for that good info. I am not likely to try powering it. it would need mounting with a different lens to be useful?
I have encountered that spike of current from power supplies. It is from the output capacitor when you connect the leads when the power supply is already on.
How does that IR filter not affect the color of the image since it is distinctly tinted blue?
The white balance would be setup to account for it since it is always there.
I think it's sensitive to dust, so you'll have to cover it with plastic when not in use. I think you should remove all cables from the board before moving the camera.
That would be true for repairing customers equipment. In this case I am taking a look at something that was being thrown out.
