How much information can be stored on a cd rom disk

This simply means the burner allocates another part of the disk to the next 'session'. This means that you can save data to your disk over and over again, but they are more expensive than the standard CDROM and a USB memory stick can hold much more data in any case.

Fairly portable. Too large to fit into a pocket, but will easily fit inside a bag. Easily scratched by general wear and tear or by not protecting it in a plastic case.

Scratches on the disk surface can damage the data being stored. Challenge see if you can find out one extra fact on this topic that we haven't already told you. Storage Devices Home. Data storage.

Basically, there is a world of difference between these. With the storage of a DVD ROM, you can see interactive multimedia programs that use hours of full-screen video to help you see movies, play games or even learn your courses. The basic reason why a DVD can store such huge quantities of data is due to its design and also the laser.

And the data layer is only half as thick as on a conventional CD, allowing manufacturers to bond two layers onto a double-sided DVD disk of the same thickness as a CD 1. This design provides tremendous storage space, although you need to turn the disk over to access the data on the other side.

Furthermore, with advancement in technologies even more data was squeezed onto one side of a DVD. By using a semi-transparent gold layer atop the reflective silver-coloured layer, the DVD can store two layers of data on one side. Using a lower-power beam, the laser can read the data from the gold layer; then, with an increase of power, it can access and read the silver layer.

This method results in slightly less than double the capacity of a single layer, but that is still an impressive 8.
