Blu Ray Recordable Diodes?

Is their any significant differences between the requirements of a blu ray player diode and a blu ray recordable diode?

I am going to do my first build and need to get a driver for the diode. I have 7.4 LiPo,s at my disposal, so what driver would you recomend?

Cheers

Yes, burners have beefier diodes in them than readers. I'd recommend the rkcstr driver (look under the buy/sell section for a thread titled "Adjustable micro laser drivers")... The driver requires 2.5v for itself, then the diode requires about 5v to 6v depending on what current you're running it at, so your LiPo's will work well at a full charge, though as they begin to die the driver will fall out of regulation. Careful not to drain your batteries too deep, LiPo's really don't like that.

Thanks, I think ile integrate a voltage monitor into the build so I dont kill my LiPo's

Well, as a GENERAL RULE, it takes more power to burn than to read BUT (very big but) this may NOT be the case with blu-ray diodes.

Here's my reasoning:

The 6x blu-ray burner drive has a powerful diode and can thus burn at 6x speeds. At the same time, it can still only READ at 6x. Now, there is also an identical version of the drive without burning capabilities, it is only a reader. It's read speed is ALSO 6x. SO you would think that if the 6x burner had the stronger diode it would have a higher read speed, yet this isn't the case.

I have a theory that for whatever reason it takes a good amount of power to read blu-ray at high speed, and I also believe that the 6x reader and the 6x writer contain the same diode and sled, but I have not yet tested this theory.

That's interesting. It would be really neat if one could make a reader burn with a firmware upgrade, or somesuch.

I have all the parts out of a few ggw-h20L 6x burner drives to do it, so I am going to be trying this in the very near future
