Dealing with disks
Back-up your life
While hard disk storage is going through the roof in terms of capacity, most PCs and notebooks now come with DVD recorders and according to Statistics New Zealand our appetite for recordable media is insatiable.
About 45 million recordable DVD and CD units were imported in 2006; with 4.7Gb on a DVD and 700Mb on a CD, thatís one heck of a lot of data back-ups, home movies, photo disks or music compilations.
Not all disks are created equal but your best bet is to buy a brand that
has a trusted market reputation. How long disks last and how accurately
they store your data has a lot to do with the user. For example if you
want optimum results donít be in too much of a hurry to burn your data
or make that compilation. If you burn at half or two thirds of the
capability of your drive itís less likely youíll pick up errors along
The way CDs and DVDs are handled can have a big impact on how long they
last. Media manufacturer Verbatim recommends holding them by the outer
edge to prevent fingerprints, grease or heat damage. Donít touch the
surface of the disc. Donít bend the disc or use adhesive labels.
There are number of brands in the writable media market including Imation, TDK and Verbatim with prices ranging between 40-80 cents a disk depending on the brand and numbers on a spindle. Verbatim for example is selling a 50 pack of CDs for $25 and 100 pack for $45. DVDs are coming down in price, they used to be $3-$5 each, now they can be under a dollar. Blu-ray and HD-DVD recordable disks however still cost $20-$30 each
