Archival Disc with 300 GB capacity to launch in 2015

Archival Disc with 300 GB capacity to launch in 2015

Current optical disc formats are less than ideal for archiving or backup purposes due to space constraints.

It is often not possible to back up your root partition to a single disc, and while it is possible to span the archive on multiple discs, it not only is inconvenient but also increases the chance of data failure.

Internal or external hard drives on the other hand offer Terabytes of space, which usually is enough to back up whatever you want to archive.

The problem here is that the method works fine for sporadic backups, but when you need to back up regularly, you will either have to buy lots of drives, or delete old backups regularly to make space for newer ones.

Business-specific archiving solutions such as tapes or cartridges offer high storage options (in the Terabyte range per cartridge) but come at a price.

Archival Disc Format


Sony and Panasonic announced the Archival Disc format officially today. The next-generation optical disc format will launch in the summer of 2015 with a capacity of 300 Gigabyte.

Both companies plan to increase that size to 500 Gigabyte and 1 Terabyte in the future.

Blu-Ray Discs support a disc size of up to 128 GB, which means that the first iteration of the Archival Disc format increases that by nearly a factor of three.

The Archival Disc specification confirms that the new format uses a double-sided disc technology with three layers per side and a data bit length of 79.5 nanometers and a track pitch of 0.225 micrometers.


Sony and Panasonic emphasize that the new format has been specifically designed for "the market for long-term digital data storage". What the press release fails to address are the benefits of the new format in comparison to existing solutions.

For example, while we know the storage size of the optical discs, we do not know how long they will last, how fast the recording speed or read speed is, or how much recordable discs and writers will cost.

No information are provided whether the new standard supports re-writeable discs as well. The key specification lists write-once as the disc type only.

The new format competes against a number of solutions. First against existing local backup solutions such as tapes, cartridges or external drives, but also against growing remote backup services.

Sony and Panasonic target the professional market with the new format first and foremost according to the press release.

Apple Launches Web Tool to Deregister Phone Numbers from iMessage

Apple today released a new web tool for users to deregister their phone number from iMessage in the event they switched to a non-Apple device. To deregister a phone number from iMessage, users simply enter their phone number in Apple's web tool, receive a free text message containing a code, and submit the code to complete the process. Users who still have their original iPhone can also transfer their SIM card back to the device and go to Settings -> Messages to turn iMessage off. 

Users switching from an iPhone to another device were often unable to receive SMS messages from another iPhone due to their phone number still being linked to iMessage. These specific errors with iMessage have been a well-known issue since 2011, which is when the messaging service debuted with iOS 5. They were also made even more apparent this past May, where a server glitch caused widespread message delivery problems. Apple was even sued over the matter in a California court, although the company cla…

Microsoft acquires iPhone email app Acompli

After accidentally announcing it a little early, Microsoft is officially confirming it has acquired email startup Acompli. The surprise acquisition means Microsoft is picking up a powerful email client for iPhone and Android in another move that further cements CEO Satya Nadella’s focus on cross-platform technologies. The Verge’s Casey Newton called Acompl "the Outlook for iPhone that Microsoft hasn’t yet built," and it seems Microsoft was equally impressed with the powerhouse email app. "We’re excited about what’s possible as we build on the app’s success and bring it together with work currently in progress by the Outlook team," the company said in a statement. "Our goal is to deliver fantastic cross-platform apps that support the variety of email services people use today and help them accomplish more." Recode first reportedthat Microsoft would make its latest acquisition official today; the company is said to be paying over $200 million for Acompli.

Apple will disconnect ‘obsolete’ first-gen Apple TV from iTunes in May

Apple has announced today it will drop iTunes support for some older devices from May 25. This includes the first generation Apple TV, and also any PC running Windows XP or Vista. The company is introducing new security changes which will prevent those devices from using the latest version of iTunes.
Apple says that the original Apple TV is an "obsolete Apple product" and will not be updated to support security changes. Only those with the second generation of Apple TV or later will be able to access the iTunes store.
Windows XP or Vista users won't be able to use the latest version of iTunes, but older Windows computers can still use previous versions without support from Apple. Those who do so, however, won't be able to make new purchases or re-download previous purchases on that computer. If you're on on XP or Vista, you'll need to upgrade to Windows 7 or later to continue using iTunes normally.
The writing was already on the wall for these devices: Wi…
