Resumen de More Bits in Pits.
The article looks at research in digital video disc (DVD) technology. Researchers are working on follow-up technology and have demonstrated an approach that could boost the capacity by 40 times more. But future movies will exceed today's high-definition resolution, and such formats will require about four times more capacity. Multiplexed optical data storage (MODS) disks could pose a near-term threat to the most advanced alternative for mass-storage optical technology-holography. After 40 years of research, the cost and engineering challenges of holographic systems are well understood, whereas MODS lacks the body of work that would allow a good comparison. Although the first holographic drives may arrive next year for professional use, consumer versions will probably wait until the next-JOUReration DVD format Blu-ray or HD-DVD has its run, typically seven years. The MODS, using DVD-like pits to encode several bits, may not appear until 2010 or later. INSET: FIRST COME, FIRST ADOPTED.
