iDisc mini CD-RWs (4x Speed, 188MB)

iDisc mini CD-RWs, which are small, rewritable compact discs with a diameter of 80mm. These are specifically rated for a maximum write speed of 4x and can store 188 megabytes of data or 21 minutes of audio. Key Information: - Format: The discs use the CD-RW (Compact Disc ReWritable) format, utilizing phase change technology to allow data to be written, erased, and rewritten multiple times, typically up to 1,000 times. - Capacity: They hold less data than standard 120mm CDs (which typically hold 700MB) due to their smaller size, making them suitable for smaller file backups or single-session recordings. - Usage: They were primarily used for temporary data backups, transferring small amounts of computer files between compatible drives, or creating custom mini-audio CDs for personal use. These discs were most popular before USB flash drives became common and affordable for everyday file transfers. ($1 each. Several in stock)
