I was wondering part way through the process if such a continuous use of the laser might be bad for the DVD drive. A completely full -RAM disk, 3x, takes 15 to 20 minutes to copy the contents to the internal drive.
Now I have about 130 hours (LP) of content on that recorder that I have to edit the commercials out of before transferring them to -R disks. Won't THAT be fun. Still, at six episodes per disk, at least I'll see some progress as I go, and I have freed up a lot of my -RAM disks.
I can’t comment specifically on your “RAM” situation because I don’t know how much laser power RAM discs require but if they are similar to –R SL discs then burning at x3 speed using a 6x burner shouldn’t heat up too much but I would still wait atleast 10 minutes between HSD burning. That’s my opinion.
Now regarding –R discs and burners I have some info from a Sony Tech guy who fixes Sony Broadcast and Production products. Sony does not really manufacture pro DVD units (they market XDCam for B&P which uses Blu-Ray technology but is more robust than consumer blu-ray) so my contact got his info from his colleague who works for Sony Consumer and is familiar with my RDR-HX780. So my info is second-hand but in my opinion comes from a very reliable source.
I specifically asked regarding my Sony RDR-HX780.
Stuff I was told:
1) Burning a 1x to 16x rated disc @ 6x or burning a 1x to 8x rated disc @ 6x requires the same laser power as long as the 8x and 16x discs are of similar quality.
2) Burning a 1x to 16x rated disc @ 6x or burning a 1x to 8x rated disc @ 6x stresses the burner because both discs require high laser power at 6x and approach the maximum limit of the deck – this can cause a lot of heat.
3) Burning a 1x to 16x rated disc @ 1x or burning a 1x to 8x rated disc @ 1x puts far less stress on the LD due to the low power level required to burn @ 1x speed. Due to the low power – the lower heat generated can disperse without causing damage.
I specifically asked my Sony pro contact to ask his Sony consumer contact to state what is the best thing I can do to prolong the life of my RDR-HX780.
4) Refrain from continually HSD burning one disc after another. After each HSD dub give the unit adequate time for the laser to cool off before HSD burning the next disc.
These decks are consumer use units costing around $300 to $500 and should be treated as consumer decks. Professional broadcast & Production decks cost from $20,000 to $80,000.So Luke my advise to you is let your deck cool off between burns when HSD burning many discs in a row
As to some of the references by some posters at this site. I would take it all with a grain of salt. Not very credible at all A couple of examples.
Someone’s “Post FAQ” here states that
T-Y 1x to 16x discs require more power than T-Y 1x to 8x discs when burning at a 8x speed. Even has a graph yet no reference to the graph. Well surprise, I have reference to a T-Y graph that states that a T-Y 1x to 8x rated disc requires the same laser power at 1x speed or 8x speed as a T-Y 1x to 16x rated disc.
Actual reference, not made up stuff TY stating same laser laser power with their 1to8x and 1to16x discs at slower burn speeds.http://ds.yuden.co.jp/Detail/download.php?filePath=../ProductData/Series/media02_e.pdf
That same person also states that the credible website Digitalfaq.com recommends the top rated Verbatim discs but only in the 8x speed. . Anyone who wishes to go to Digitalfaq.com will see that this is not true some would say that it’s outright lying. In fact Digitalfaq.com recommends any speed Verbatim AZO discs including 1to16x speed.
Actual reference, not made up stuff digital faq recommending 1to16x media as much as 1to8x media.
In fact Digitalfaq.com states that Mitsubishi (Verbatim branded) 1x-16x MCC DVD-R tend to work well for 1x real-time burning.
