First we had CD’s that brought us 700MB of storage, then DVD’s brought us 4GB, HighDef discs with 50GB all of which scratch unbelievably easy to ruin all the data stored on them. Not learning from our lessons of the past now new optical media is promising to store up to 1.6Tbytes on a single disc because of holograms.

The product being launched by InPhase is the Tapestry 300R drive and media, which has a capacity of 300Gbytes and a transfer rate of 20Mbytes a second. The first-generation product is write once, read many, and a single drive will cost about £9,000. One disc will cost about £90. By way of comparison, an enterprise-class tape drive costs about £15,000 and a mid-range tape drive costs about £2,000.

InPhase expects to develop and release three generations of drives and media. From the initial specifications outlined above, it hopes to move to a second-generation device in 18 months to two years, which will provide 800Gbytes of capacity and a transfer rate of 80Mbytes a second. A third system with 1.6Tbytes of capacity and a transfer rate of 120Mbytes a second should be available in three to four years.
