50 DVDs' worth of data in a credit-card sized package

 I'm a little skeptical. All the report talks about is reading bits, and says nothing about writing bits. Sure, it's great to have an ultra-sensitive read head, but writing data at that density is no small feat.

Note that the chart on this page is logarithmic, not linear. In 1996, drives still cost more than $1 per megabyte, you can now get them for around $1 per gigabyte.

The real win here is that current CMR heads get nailed by supermagnetive effects when densities hit somewhere between 100 and 200 Gigabits/square-inch -- just the thermal energy of the drive is enough to flip bits. Current production top is around 80Gb/In^2, with most drives using less. This trick means that storage prices will coninute to plummet.

 Yeah, but does it make it any easier for me to email the Superbowl to my friends?

 These breathless announcements should come with a certified "time to market." I keep hearing about all these exponential storage breakthroughs. Does someone have a graph of the price/gb for the past five years?
