Yes, Blu-ray disks are more scratch resistant than DVDs. By using Durabis, TDK corporation have significantly reduced the number and effect of scratches to a disc surface.
If costs are important, blu-ray writers and discs are very affordable, compared to other data storage solutions. Last but not least, blu-ray discs are suitable for long term data archiving, since they last at least 50 years and are predictably forward compatible with the newest devices.
You won't get high-definition movie viewing on your DVD, just 480 SD. On the other hand, Blu-ray is made for HD, and you'll get the best picture possible, with 1080 HD capability for your Blu-ray movies. So if you are looking for a quality picture, Blue Ray is the clear winner.
When stored properly (away from heat, humidity, UV rays), tapes can last 30 – 50 years. According to the Canadian Conservation Institute, which publishes a paper on media longevity, BD-R discs are expected to last between 5 and 20 years, depending on the material they are made out of.
Blu-rays deliver the best picture and sound experience.
For example, Netflix maxes out at 17Mbps, while Apple TV+ maxes out at around 41 Mbps. The very best Blu-rays, the 4K Ultra HD versions, can deliver a 4K picture with maximum video bitrate of 128 Mbps.
One of the most significant advantages of Blu-ray is its increased disc capacity. Blu-ray discs can hold much more data than DVDs, allowing for stunning high-definition video playback at up to 1080p resolution. This means you can enjoy movies, TV shows, and other content with unparalleled clarity and detail.
Under ideal conditions, a high-quality Blu-ray disc can last for decades or even up to a hundred years. However, frequent use or mishandling can significantly reduce the lifespan of the disc.
Blu-ray Discs definitely cost more to manufacture than DVD, for a number of reasons: Because the cost of replicating equipment is much higher than for DVD, there are far fewer plants which can produce BD-ROM discs (a Sony division holds a large share of the market), so there is less competition.
A Blu-ray can hold about 25 GB of data, which allows for more high-definition information. It can hold about 13 hours of standard definition information or about two hours of high-definition information. Some of the double-layer discs out there can hold substantially more.
Among the manufacturers that have done testing, there is consensus that, under recommended storage conditions, CD-R, DVD-R, and DVD+R discs should have a life expectancy of 100 to 200 years or more; CD-RW, DVD-RW, DVD+RW, and DVD-RAM discs should have a life expectancy of 25 years or more.
While you can't stop disc rot once its happened and you have no control over the way your discs were manufactured, there are things you can do to minimize the chances of disc rot from happening. Keep your discs in their cases. Not in stacks, not in paper sleeves. Keep your disc collection in a cool, dry environment.
There are a few reasons why Blu-ray technology never really took off. Firstly, the cost of Blu-ray players and discs was always quite high, so many people stuck with DVDs instead. Secondly, streaming services like Netflix became very popular, so people didn't need to buy or rent physical discs anymore.
Streaming is a popular way to consume media these days, and DVD sales have declined by 86% since 2008. Curiously, many stores fill their shelves with DVDs and Blu-rays, and Technicolor Home Entertainment Services plans to ship as many as 750 million discs in 2022.
If you're wondering “are CDs worth anything”, you should know there's a lot of value in those old CDs, especially if you're an audiophile. These days, some streaming services are losing their luster – with some famous artists like Neil Young taking down entire catalogs.
The disc should be stored in its case and placed vertically, like a book, on a shelf. Long-term horizontal storage, particularly in a heated environment, can cause the disc to become permanently bowed.
The higher quality discs will have a longer life than lower quality discs. As you said some websites state that a Blu-Ray RW disc can be rewritten between 100 to 1000 times. Once again, this number is dependent upon the disc and the care that is taken with the disc.
Blu-ray will only play on Blu-ray specific drives and players. You cannot play a Blu-ray disc on a DVD or CD player. However, there are several brands of Blu-ray disc players and many new PC's are coming with Blu-ray drives installed. Sony Playstation 3,4 and the Microsoft Xbox One are also a Blu-ray enabled device.
What is the next technology after Blu-ray? Unfortunately, UHD Blu-ray is probably the last physical disc format - which means streaming is what will be used for the foreseeable future. There are rumors of a couple of disc formats being developed - but nothing formal.
The name Blu-ray is derived from the blue laser which is used to read and write to Blu-ray discs. Compared to a red laser used to read DVDs, a blue laser allows for a much greater density of data to be stored on a disc.
