This shipment, I received our first shipment of the brand new Kodak Archival media . These thin synthetic wallets have been silverised with a metal finish and protect against damaging light and temperature - the packaging says they are a 'metalised nano layered wallet and shield against light and temperature and are environmentally friendly. There are two factors to bear in mind when you are observing the archival life of recordable media and in particular DVD, Compact disk and Blu-ray discs - their shelf life and their longevity after recording. Who would want to burn a disc and then pop it safely into a case only to come back to it a couple of years later to get a number of treasured photos or a backup only to find there were media read errors due to Disc deterioration - no one, and nearly all the time this would be more than a catastrophe, having said that I still have Cds that I recorded more than 9 years ago and are still fine - they were not even specifically archive disc and not stored in any very special environment!. Disc shelf lifespan is something you have little control over but the quantities of disc media sold these days means that each disc you buy should be relatively 'fresh' out of the packet. Burning media for archive backup reasons is a different matter from burning for production or short term data hand over between offices. The most common use of DVD-R currently is for archive of video and audio tracks, photographs, images, etc, this means that you need to be absolutely sure the files can be read/write or played back in the years to come without the disc returning data reading faults. Think it or not but the definite life cycle of a recorded piece of media whether that be a Compact disk, DVD or Blueray discs depends on storage quality, if humidity and in particular temperature are not within manufacturers specifications media will deteriorate and data will be gone as the recordable layer on these types of discs is typically an organic dye. Nevertheless, the strategy for tolerance on these specs are fairly forgiving as far as CD, DVD and Blueray disc media are concerned. heat as infrared and daylight as UV daylight are established to have the most serious effect on disc degradation, the most simple reason is to look at how a photograph will fade if left in the sun on a window sill - much the same can and will happen to your burned media if left to endure from these two detrimental effects. This is why museums opt to deposit their exhibits in cardboard boxes often in heat and humidity controlled environments, so short of casing up your recorded discs in blackout materials and placing them in the loft within a vivarium at a constant heat you should be looking for a different solution to protect your media! The latest Kodak pouches are made of a plastic type plastic material that has been layered with metal, on the packaging it is described as a 'metalized nano finish}' and it looks like the wallets have been sputtered with aluminum or some other silver coloured metal. This gives a sleeve or wallet that you thats non transparent it’s this finish that keeps heat out as well as hurtful UV light. So to the results - my conclusions having examined these up-to-the-minute sleeves from Kodak - The Kodak Archive media wallets - I am sure that they are going to be a very good addition to the archival strategy for those clients and users that have sensitive and precious data backed up onto DVD-R, CD and Blu-ray - they effectively block the UV Light from reaching the discs recorded layer and are tremendously thin but sturdy. The pouches can also be labeled or written on with a permanent marker, all round an first-rate product and at in the region of £6 for 50 well worth the price to make sure the future of your data, video or photographs. The long term archival policy is something all of us should consider but it can be said most don't bother, so next time you have a few treasured data on a disc suppose carefully how you will store it just in case you could do with to achieve at it not just in a few weeks time but perhaps quite a few years later. Hard drive storage isn’t the best solution to long term data backup, they are notorious for failing at the exceedingly moment you require that crucial photograph or video - and guess what, you forgot to make that backup copy to media! People have said that DVDR and CD are on their way out, but in this day and age of almost everything available in more and more larger chunks of data and quicker download times are we moving to a chuck away way of life in that people consume their download ‘fix’ and straight away delete it or are there continually going to be bits you could do with to save? Well I say those important photo memories require to be kept back separate away from your PC, disc station or mobile device (all of which will go wrong at a number of stage or be lost stolen or damaged and the present best choice to achieve that is to back it up onto DVD, CD or Blueray discs and accomplish into the routine of storing these media in your own archival system, all you could do with is a disc wallet and a few of the Kodak disc pouches and your photo memories are protected for your decendants to look at and grin!
