OFF-TOPIC: commercial DVDs without label
When I buy DVDs, occasionally I get one that has the pertinent
information on a ring around the hub but has no label covering the DVD. Any thoughts on why that's done? The latest one (bought used) has a normal case and cover and the remains of the security stickers on top and bottom; the DVD is meant to be played on one side, not both sides. -- Thank you, Jo-Anne |

Hi, used to be one side was standard 4/3 format and the other side was the same movie in wide screen format. Rene |

Wow, didn't think that could be engineered. |

The focal length of the optics has to change, to pick up the second layer. Reading is from one side of the disc only. https://publiclab.org/notes/MrBumper...action-grating https://i.publiclab.org/system/image...ublelayer1.gif I wonder how the uncorrected error rate differs on the two layers.

I'm afraid I wasn't clear about what I was asking. The commercial DVDs I'm referring to are movies that come in regular movie DVD cases and are only one-sided. (I do have some that are widescreen on one side and full screen on the other, but these aren't the ones I'm asking about.) Normally, they would have a label that covers the entire DVD on top--but a few have no label, just the movie title and other relevant information on a ring around the hub. You can see an image of this kind of DVD for the movie The Big Easy on eBay at https://www.ebay.com/itm/The-Big-Eas...QAAOSwx2har~8G The disc images are the far-right ones under the main image. The one on the left is the top side and looks like some of the DVDs I have. They appear to be genuine. -- Jo-Anne |

Apparently the pressed ones go up to DVD-17 ("Figure 11"). Shocking. You'd think it would be too thick. https://www.clir.org/pubs/reports/pub121/sec3/ I wonder why I've never seen any reference to that in adverts, like "this DVD drive reads DVD-17" ? Paul |
