What does the BD-RE standard define in the context of Blu-ray discs?

1. Read-only disks

2. Rewritable disks

3. Double-layer disks

4. Data disks

The correct answer is: Rewritable disks

The BD-RE standard defines rewritable Blu-ray discs. This means that these discs can be recorded on and erased multiple times, allowing users to reuse the media for different data or video content. Blu-ray discs that use the BD-RE format can accommodate large amounts of data, making them suitable for high-definition video storage as well as for backing up data. The flexibility of being rewritable is a key feature that sets BD-RE discs apart from other types, such as BD-ROM, which are read-only, and BD-R, which are write-once discs. The BD-RE specification ensures compatibility with rewriting technology, which includes certain methods and technologies for writing and erasing data safely and efficiently without damaging the disc. This makes it particularly useful for projects that require frequent updates to the data stored on the disc.
