The duo wants a 300 GB capacity disk by 2015
Sony and Panasonic have announced that they have signed a basic agreement that will see them jointly develop a new standard for professional-use optical discs. The objective of the two companies is to expand their business for long-term digital data storage by developing an optical disc with a capacity of at least 300 GB.
The two companies are directly targeting businesses that need archival storage including motion picture, broadcasting, and cloud service industries.
Optical discs are likely to remain a preferred long-term storage option because the discs are dust- and water-resistant. Another significant benefit of using optical discs is that they allow inter-generational compatibility between different formats -- that means older optical formats can be read on current generation optical drives.
Sony and Panasonic hope to make the 300GB optical disc available by 2015.

Digital software stored on a vinyl LP is most definitely digital storage.
It is not the storage medium, it IS the way the data is written and read. Analog sound recording equipment has been used for digital storage for as long as there has been digital storage.
Examples from the 1980s
The C2N datasette from Commodore. It was an analog cassette recorder with a digital interface to the Commodore computer tied to the microphone input. This direct connection to the I/O pin on the CPU avoided the problem of sound levels encountered by the computers that used the standard microphone jack for output to the recorder and the earphone jack for input to the recorder.
The Sinclair computers (ZX-8x TS-1x00 among them) used an off the shelf analog recorder (cassette or reel-to-reel were most commonly used) and the digital signal was recorded as analog audio of hi & lo frequency sound.
These and other computers that were able to use analog cassette tapes could also receive broadcast recordings and correctly load them. You just connected the data input to the radio speaker or recorded the broadcast on tape (cassette or reel). Several broadcasters around the world offered these as ordinary consumer broadcasts for popular computer models. This method of data transmission is still used in the SW community.
