A couple of future media storage formats (might invade our home systems soon... or not):

The HVD:

Holographic Versatile Disc (HVD) is an optical disc technology that would hold up to 3.9 terabytes (TB) of information. It employs a technique known as collinear holography, whereby two lasers, one red and one green, are collimated in a single beam. The green laser reads data encoded as laser interference fringes from a holographic layer near the top of the disc while the red laser is used as the reference beam and to read servo information from a regular CD-style aluminum layer near the bottom.

Holographic Versatile Card:

The Holographic Versatile Card (HVC) is a data storage format by Optware; the projected date for a Japanese launch had been the first half of 2007, pending finalization of the specification, however as of March 2008, nothing has yet surfaced. One of its main advantages compared with discs is the lack of moving parts when played. They claim it will hold 30GB of data, have a write speed 3 times faster than Blu-ray, and be approximately the size of a credit card. At release, the media will cost about ¥100 (roughly $1) each, reader devices are set to cost about ¥200,000(roughly $1800) while reader/writer devices are to cost ¥1 000,000 (roughly $9000) each.
