5.0 out of 5 stars The best recordable DVD format, 26 May 2008
This review is from: Panasonic 3x speed, 4.7GB, 5 pack DVD-RAM Disc (Accessory)
With so many recordable DVD formats around these days it can be difficult not only to find one that works for you but also one that you can have total faith in. DVD-RW and DVD+RW are arguably the most common formats, with DVD-RAM often being overlooked by hardware manufacturers, possibly as it was originally developed for backing up computer data rather than as a storage medium for recorded TV. This is a shame, because RAM has a number of significant advantages over both -RW and +RW that should by now have put it firmly in the lead as the preferred recordable DVD medium.

The first advantage it has is that, according to manufacturers, a DVD-RAM disk can be recorded over up to 100,000 times as opposed to the 1,000 times of its opponents. I've yet to see any firm evidence to back up this claim, and in reality most of us would never need such a capability, but the increased reliability of RAM over its rivals is fairly well documented. Another advantage it has is that RAM recorders verify the data as its written, so you can begin watching a program you're recording half way through recording it - you can start recording a film, go off and make a cup of tea, then come back and begin watching from the start as the recording continues.

The main advantage, however, has to be that information on a RAM disk is stored and read in the same way as that on a computer hard drive. If you record 4 half-hour programs onto a -RW disk, then delete the second and fourth ones, you're left with 2 half-hour slots free rather than 1 full hour one. On a RAM disk, units of information can be spread over the entire disk, exactly the same way as it can on a hard drive, so the two half-hour slots would be seen as a full hour. This also makes editing recorded TV much easier, giving you the ability to assign chapters and to delete easily any unwanted sections without affecting the rest of the recording.

I have used Panasonic DVD-RAM disks in my Panasonic DVD recorder and as a way of regularly backing up the data on my Vaio (and before that my Toshiba) PC for a total of around 5 years. In that time, I haven't had a single loss of information and the quality of the TV recordings hasn't deteriorated in the slightest despite the considerable use each disk has had. I have complete faith in the format not only as a way of storing my valuable data but also as a way of keeping copies of my favourite TV shows. Quite simply, I wouldn't even consider buying either a new PC or a new DVD recorder if it didn't have the ability to use DVD-RAM.

hi my dvd panasonic ram disc is coming up as unformat on my panasonic recorder.i have tried to reformat and the disc is coming up as a none recordable disc.can any kind folk out there offer any words of wisdom.
could the disc have perished due to dust/age or the recorder possibly knackered.recording ordinary discs has become hit and miss whether the machine accepts the discs.(dmr e55)

Hi Stephen

I've never had any problerms like this so I don't know if I can be much help, although it sounds like the laser may need cleaning. Have you tried cleaning it? I'm told it often takes several passes for a cleaner to get the job done properly.

I use these discs, they work much faster than other formats for starting up and being read, also forwarding or reversing speeds are faster. Personally, mine wear out after around 200 recordings, that's fine by me although not quite the 100,000 times suggested!
