The Optware Holographic Versatile Card (HVC) is only as big as a credit-card but stores 30GB of data.
30GB is about 6 times more than a DVD can store and in closer to the capacity of next generation DVD formats like Blu-ray or HD DVD.
A HVC costs about 90 cents. A HVC drive is supposed to cost $1,800.
I am not sure where the market for the Optware HVC holographic disc will be.
