Mempile's TeraDisc fits 1TB on a single optical disc
We've heard a lot of talk about the death of optical media, but for inexpensive high-capacity storage, it's pretty hard to beat — which is why the TeraDisc, from Israel's Mempile, look like it has such promise.
Context & Ripple Effects
Mempile's TeraDisc is the latest step in a capacity race on DVD-sized media: a 300GB disc challenging DVD surfaced back in November 2005, and just weeks ago researchers demonstrated microholography squeezing 500GB onto a DVD-sized disc. Mempile's claim of 1TB — roughly 40 HD movies per CD-size medium, per the company — doubles that again.
The announcement lands while commentary questions whether optical media has a future at all, which is why Engadget and TFOT, which ran the full technical rundown the same day, both frame it as evidence that inexpensive high-capacity discs are hard to beat.
First-order effects
- Mempile moves to the front of the high-capacity optical pack, leapfrogging the 500GB microholography demos reported earlier this summer with a claimed terabyte on a CD-sized medium.
Second-order effects
- Drive makers and archival-storage buyers get a candidate cheap bulk tier to weigh against hard disks and tape, forcing the competing high-capacity disc research efforts — 300GB-class and 500GB-class — to justify their roadmaps against a terabyte benchmark.
Third-order effects
- If the doubling cadence from 300GB in 2005 to 1TB in 2007 holds, optical media's viable role shifts from consumer content distribution toward deep-archive storage, where cost per terabyte matters more than read speed — though lab demos like these still have to survive commercialization.
The trend: Optical storage research is racing toward terabyte-per-disc capacity to carve out an archival niche even as optical's mainstream role is written off.
