He estado informándome de una cosa que habÃa oÃdo y que al parecer está al caer para el añ que viene: ya existe una nueva tecnologÃa
viable para almacenar información es soportes que no sean dispositivos ópticos ni magnéticos.
Al parecer combina la grabación en un nuevo tipo de soporte, un nuevo polÃemro que se han inventado, con una nueva froma de organizar lo que se está almacenando, y que alcanza unos niveles de densidad de información flipantes.
Lo que habÃa oÃdo es que
quieren lanzar para el 2.006 discos de 300 Gb, y para el 2.009 dicen que tendrÃan unos de 1.600 Gb.
En resumen: que por fin voy a poder tener la discografÃa de Joselito y Manolo Escobar toda junta para oÃr en el metro!!! wowwwwww!Â
Â
os dejo dos notas de prensa que explican con más detalle el asunto.

FOR RELEASE ON: MONDAY, APRIL 18, 2005
LAS VEGAS, NV -- InPhase Technologies, the leader in holographic data storage, announced today that it has successfully demonstrated
a data density of 200 gigabits per square inch, significantly higher than any other optical format. InPhase achieved this breakthrough by using its patented polytopic recording method, which will be implemented in all generations of the Tapestry drive family.
The first generation drive, targeted at a 300 gigabytes (GB) capacity on a single disk, will be available in 2006.
This will be followed a family of products ranging to 1.6 terabyte (TB) capacity in 2009. Holographic storage delivers high capacity by recording data throughout the volume of the recording material, and not just on the surface A data page of approximately 1 million bits is recorded in one exposure of the laser. Each data page is located at a unique address within the material and several hundred pages of data, each with their own unique address, are recorded in the same location of the medium. A collection of data pages is referred to as a book.
This new recording technique enables more holograms to be stored in the same volume of material by overlapping not only pages, but also books of data. This dramatically increases the storage density.
This new recording method is implemented in conjunction with an optical architecture developed by InPhase, which uses optical lenses with a high numerical aperture (NA). The combination of the new recording method and high NA lenses results in a smaller page size that provides a 10X increase in achievable data density. This also increases the data transfer rate, and InPhase has demonstrated a transfer rate of 27 megabytes (MB) per second at density.
InPhase was able to deliver this latest innovation through a $2.77 million grant awarded in 2003 by the National Institute of Standards and Technology's (NIST) Advanced Technology Program (ATP). The purpose of the grant was to develop advanced holographic recording technology that would lead to the commercialization of the first 1 TB holographic data storage system. This grant was the second that InPhase had received from the ATP in 2002-2003. The Advanced Technology Program has been a critical source of funding for breakthrough technology developments that have the potentially broad economic benefits to the United States.
"The InPhase legacy of persistent invention has produced numerous breakthroughs on the road to commercial holographic recording systems. This will impact data storage options for consumers and professionals alike," said Kevin Curtis, chief technology officer of InPhase Technologies.
The density milestone was achieved using InPhase Tapestry blue media, which is sensitive to 407-nanometer wavelength, and has a recording material thickness of 1.5 mm. Approximately 1 million bits of data were recorded per page, and 252 pages were recorded in one book. A total of fifteen books of data were overlaid in one location. InPhase is conducting the first public demonstration of a holographic prototype at the National Association of Broadcasters (NAB) convention in Las Vegas, April 18 through April 21, at the Maxell Corporation of America booth #C8530 in the central hall of the Las Vegas Convention Center. Hitachi Maxell Ltd. is both an InPhase investor and development partner.
INPHASE TECHNOLOGIES CONDUCTS FIRST PUBLIC DEMONSTRATION OF WORLD’S FIRST HOLOGRAPHIC DRIVE PROTOTYPE AT NAB 2005; HERALDS "NEW ERA OF STORAGE" InPhase and Maxell Corporation of America Demonstrate Tapestry™ Holographic Drive Prototype With Turner Entertainment Networks Content, and Pegasus Disk Technologies Windows Connectivity
FOR RELEASE ON: TUESDAY, APRIL 12, 2005
LONGMONT, CO -- InPhase Technologies, the leader in holographic data storage systems and media, today announced that
it will conduct a public demonstration of the world’s first prototype of a commercial holographic storage device using video clips provided by Turner Entertainment Networks. The demonstration of the InPhase Tapestry™ drive will be conducted with Hitachi Maxell at the National Association of Broadcasters (NAB) convention in Las Vegas, April 18 through April 21, at the Maxell Corporation of America booth #C8530 in the Central Hall of the Las Vegas Convention Center. Maxell Corporation of America is a wholly owned subsidiary of Hitachi Maxell. The prototype is the foundation for a 300 gigabyte (GB) drive that can store more than 35 hours of broadcast-quality high-definition video on a single disk. The family of InPhase Tapestry holographic drives will have capacities that range to 1.6 terabytes (TB) on a single disk.
A breakthrough in data storage, the InPhase prototype demonstrates a new generation of data storage, well beyond magnetic and optical formats, which capitalizes on the company’s leadership position in both holographic drive and media development. InPhase has created a new class of photopolymers, and the delivery of a stable recording device, to achieve a working commercial holographic system. The initial commercial units will be delivered to original equipment manufacturer (OEM) customers in 2006.
InPhase has architected an advanced technique, polytopic recording, which provides greater data density by overlaying "books" of data, rather than pages of data.[/b] The InPhase polytopic technique eliminates the space between books of data, thereby increasing data densities. This innovative technique will be implemented in all generations of the InPhase Tapestry product family.
"Today, the professional video industry will see a conclusive demonstration of the next phase in digital recording. The InPhase Tapestry prototype heralds a new era of storage, moving holographic storage from research to commercialization," said Nelson Diaz, president and CEO of InPhase Technologies. "We have successfully developed, through a collaborative approach, a breakthrough for a wide array of recording and archive applications – from enterprise to consumer – that will lead to more secure, high-capacity, long-life storage at more cost-effective prices."
The InPhase Tapestry system has been evaluated by numerous leaders in the professional film and video industry for a wide range of applications, including archive, acquisition, editing, and effects for high-resolution video.
"We have the need to archive high-definition movies as large files and, yet, be able to retrieve them quickly when needed for air. Until now, there has been no cost- effective, practical way to meet our volume and throughput requirements. Holographic storage appears to be the perfect answer," said Ron Tarasoff, Vice President of Broadcast Technology & Engineering at Turner Entertainment Networks.
The prototype drive records data into InPhase’s patented two-chemistry Tapestry photopolymer write-once material. The recording material is 1.5 mm thick and is sandwiched between two 130 mm diameter transmissive plastic substrates. Hitachi Maxell, Ltd., a key investor and development partner of InPhase, is developing high-volume media manufacturing technologies and has designed and developed the disk cartridge for easy integration in automated library systems.
The Tapestry prototype drive has a small computer systems interface (SCSI) interface and is using the Pegasus Disk Technologies Windows device driver. InPhase is working with Pegasus to provide file system connectivity for the Windows operating system as part of a total data storage solution. From a system perspective, the device presents itself like a drive letter with complete random access, in less than 200 milliseconds, to any file on the holographic disk. This demonstrates the ease of use and integration of holographic technology by hardware OEMs, original design manufacturers (ODMs), and software providers.
