An Optical Disk
For what storage medium are phase change alloys used?
DVD and RAM are not permanent storage devices.
An optical storage medium such as a CD or DVD can store audio and video files, respectively. DVD's are also capable of storing images and other data.

Optical dense refers to the index of refraction. If one medium is optically denser than another, then its index of refraction is larger, meaning the speed of light in the optically denser medium is smaller.
Backing storage refers to non-volatile storage systems used to retain data permanently, such as hard drives, solid-state drives, and optical discs. It serves as a complement to primary storage (like RAM) by providing a larger capacity for data retention, even when the power is off. A media track, on the other hand, is a concentric circle on a storage medium, such as a hard disk or optical disc, where data is recorded and retrieved. Each track can hold a significant amount of information organized into sectors, which are the smallest units of storage on the medium.
No, optical medium and optical density are not the same. Optical medium refers to the material through which light propagates, such as air, water, or glass. Optical density, on the other hand, is a measure of how much a material can refract or absorb light, which affects how light passes through it.
An optical storage device is an electro-mechanical unit that can save and retrieve (write and read) information on a special disc medium using a laser light. Optical drives are designed to work with several types of media: CDs ("compact disc"), DVDs (digital versatile disc" or "digital video disc") and Blu-ray discs.
