There is nothing on any BD drive on page 83 of the document you linked. It is describing the media, not the drive. What is of interest regarding the drive though is this paragraph from p.84:

This is an addition for BD 2.0 which is the spec allowing the creation of 66 and 100 GB Blurays. This confirms that current drives won't be able to read BD 2.0 media if anything - the exact opposite of what you're saying.

Thanks for actually reading and discussing this issue.

Version 2 drives/disks are those that comply with the 2010 BD-R whitepaper and have implemented the 2010 Sony patent. I.E. any modern BD drive can read a Version 1 and Version 2 disk while a Version 1 drive can not read a version 2 disk because the track information on the disk is inverted to insure it can't be read.

There is a 2010 patent from Sony which confirms modern blu-ray drives can support 4k blu-ray. The patent discusses a modification to either the coming 4 layer BDXL in the 2010 blu-ray whitepaper or 3 layer 4K blu-ray disks to make them unreadable on older blu-ray drives by inverting the track information. A software change to later higher spec standard blu-ray drives makes them able to read this inverted track information.

For example, if a new version of the Blu-ray Disc that incorporates a multi-layer structure of at least three layers (hereinafter called the Ver. 2.0 disc) becomes commercially available in the future, it could happen that a user would load a Ver. 2.0 disc into a Ver. 1.0 drive.

Basically, because the Blu-ray Disc format is the same, recording and playing back a Ver. 2.0 disc on a Ver. 1.0 drive would not be absolutely impossible. However, if the Ver. 2.0 disc is achieved by using higher density and more layers, it can be assumed that the various types of specifications with which the Ver. 1.0 drive is provided would not the adequate.

Therefore, in a case where recording and playback of a Ver. 2.0 disc are done on a Ver. 1.0 drive, there is concern that recording errors and playback errors would occur with greater frequency.

So a change to the specs of a blu-ray drive would make it usable for 4K. That's what the 2010 blu-ray BD-R whitepaper was all about. They had from 2010 to do this. Sometime after 2010 modern drives could read 4 layer BDXL which means they could easily read 3 Layer commercial disks.

1) A UHD disk is three layers and higher density and BD-ROM Version 2 drives can read this. We have known that BDXL drives can read 4 layer recordable disks. This paper confirms that BD-ROM can read 4 layers much less three
2) There is no UHD drive!!!!!
3) The BD Version 2 drive was envisioned in 2010 (Patent) and incorporates the 2010 BD-R whitepaper.
4) The Panasonic-Sony firmware tweak to the drive to read the increase in the density of the disk media is from 2010 and is mentioned in the 2010 Version 2 patent.
5) A BD version 2 drive is a modern blu-ray drive and sometime after 2010 all BD drives are version 2 drives and can read version 1 and 2 Disks.
6) There is no UHD drive mentioned!!!!!

There is no UHD drive mentioned!!!!. The PS3 BD-ROM 2X speed version 1 drive can not read a BD-ROM version 2 disk whether it has HD or UHD media, two layers or three layers.... A PS4 modern blu-ray 6X speed version 2 drive can read a Version 1 HD media disk and a Version 2 HD or UHD media disk.

The HD or UHD media on the disk does not make the disk format HD or UHD, it's always a Blu-ray disk that is read by a blu-ray drive, only the media and required read rate changes; 1080P HD requires a 1X drive and UHD requires a 4X drive. A 2 layer 50GB version 2 disk can support HD or UHD and some UHD movies to reduce costs will come on what amounts to version 1 disks with inverted track information.

On January 1, 2010, Sony, in association with Panasonic, announced plans to increase the storage capacity on their Blu-ray Discs from 25 GB to 33.4 GB via a technology called i-MLSE (Maximum likelihood Sequence Estimation). The higher-capacity discs, according to Sony, will be readable on current Blu-ray Disc players with a firmware upgrade. No date has been set to include the increased space, although in 2010 Blu-ray.com reported that "it will likely happen sometime later this year."[78]

The usable data rate of a Blu-ray Disc drive can be limited by the capacity of the drive's data interface. With a USB 2.0 interface, the maximum exploitable drive speed is 288 Mbit/s or 36 MB/s (also called 8× speed)

What Ito would have us believe is that Sony used 2003 spec drives in a late 2013 PS4 when in 2010 Sony introduced the version 2 BD drive specs. Further Sony would need to have the drives special made to not support UHD while Microsoft used cheaper off the shelf drives and can support UHD Blu-ray with version 2 drives. You see how stupid and insulting this is to anyone who did the research or Knows what modern BD drives can support. When you add that Sony is counting on UHD to turn around their business including Blu-ray disk sales it's doubly insulting.

PS Vita is truly an anomaly amongst handhelds. A FUCKING powerhouse that's that

What's missing in the handheld martlet is its connection with communication I.e. Cell Phones, that's the obvious.

Graphics, battery life, storage can all be enhanced on handhelds

There is no way that UHD BD will have anywhere close to that meaningful an impact on Sony's bottom line.

Adam, I said UHD and meant in all it's forms and that includes multi-stream 720P or 1080P using HEVC.

A UHD blu-ray platform can support ATSC 3.0, Multi-stream sporting events using HEVC, IPTV either HD or UHD using HEVC and the Panasonic-Sony digital bridge proposal that will support extended color space supported by some 1080P TVs as well as streaming HD and UHD from BD disks copied to hard disk.

The CE industry is not counting on UHD BD, they plan to have a list of features a UHD player can support. PS4 and XB1 will be the first to support the new features.

Sony Electronics eyes premium path

From 2012 Sony shows off new Sony 4K cameras & more 4K content is on the way

Notice the 4K server is blocked out...can you think of any reason beyond it's a PS4 sitting on it's side?
