DiscGrößen

DiscGrößen refers to the diameter of optical discs, commonly used for storing digital data such as music, videos, and software. The most prevalent disc sizes are 120mm and 80mm.

The 120mm disc, widely recognized as the standard CD (Compact Disc) and DVD (Digital Versatile Disc) size, has a capacity that varies depending on the specific format. A standard CD can typically hold around 700 megabytes of data, while a single-layer DVD can hold approximately 4.7 gigabytes. Dual-layer DVDs offer higher capacities. Blu-ray discs, which are also 120mm in diameter, offer even greater storage, with standard single-layer discs holding 25 gigabytes and dual-layer discs holding 50 gigabytes.

The 80mm disc, often referred to as a mini-disc, is smaller and typically has a lower storage capacity. These discs are commonly used for smaller data storage needs, such as business cards or certain types of audio recordings. Their capacity is generally much less than their 120mm counterparts, making them suitable for more specialized applications.

The standardization of these disc sizes has been crucial for ensuring compatibility across various playback devices and drives. While newer technologies like flash drives and cloud storage have become more popular, optical discs, defined by their specific DiscGrößen, remain relevant for archival purposes and in certain entertainment and data distribution channels. The physical dimensions of these discs dictate the amount of data that can be encoded and read by laser technology.
