The time to read the complete tape might be longer than the time to read a blu-ray, but in terms of data rates modern tapes are still about a factor of 3 ahead of optical disks (160MB/s for Ultrium 6 vs 54MB/s for Blu-ray 12x).
- kalleboo 13y agoI wonder what happened to the idea of multiple optical read heads. When CD-ROM drives were trying to maintain 52x read rates, I think Pioneer or someone made a drive that read at twice the rate using 2 separate optical assemblies.
