Optical Disc

The Magneto Optical Disc (MOD) and CD (Compact Disc) recording formats represent significant milestones in digital data storage technology. Developed by Sony and Philips in the early 1980s, the CD format transformed the music industry by providing a high-quality, compact medium for storing audio data. CDs utilize laser technology to read and write data on a reflective disc, ensuring precise reproduction of sound without degradation. Similarly, the Magneto Optical Disc (MOD) format, developed by Sony and Hitachi, utilizes magneto-optical technology for data storage. MOD discs employ a combination of laser and magnetic fields to read and write data, offering high reliability and longevity. While CDs revolutionized music distribution, MOD discs found applications in data backup, archival storage, and professional recording. Together, these formats have significantly influenced digital data storage and remain relevant in various industries despite advancements in technology.
