Sony CD-RW Rewritable Disc - 700MB, 4x Write Speed, 80 Min, 120mm

Sony's CD-RW rewritable disc gives you 700MB of storage that can be recorded, erased and re-recorded hundreds of times over — ideal for data you update regularly rather than archive permanently. Standard 120mm format means it works in any CD-RW-capable drive.

Unlike a write-once CD-R, a CD-RW disc can be reused, making it a practical, lower-waste option for backups, temporary transfers and everyday burning tasks where the content will change over time. This disc records at up to 4x write speed and holds roughly 1.33 hours of audio, or 700MB of data.

Good to know

A CD-RW compatible optical drive is required to write to this disc — standard CD-R-only or DVD-R-only drives may not support rewritable media, so check your drive's specifications first. Because CD-RW discs use a different reflective layer to CD-R, some older standalone CD players may not read them reliably; if the disc needs to play in a car stereo or hi-fi, a CD-R is generally the safer choice.
