WebTypical applications for optical media. CD – Audio and small amounts of data; DVD – Standard definition movies and data; Blu-Ray – HD video and large amounts of data; DVD. Despite being the same physical size, a DVD can hold more data than a CD. To achieve this, a more tightly packed spiral track is used to store the data on the disc. WebOne of the biggest advantages of optical storage over other storage media is durability. Optical discs are not vulnerable to data loss due to power failure like volatile memory, and they're not as subject to wear as non-volatile memory such as HDDs and flash SSDs. Optical discs are also much sturdier than magnetic tape, which is the leading ...
