Breaking News – River Media Professional Launch New Pro CD-R Prism Disc

Our new blog post brings a rarity in today’s day and age, the launch of a new CD-R.

The culmination of over 21 years of research and development, the River Media Pro CD-R Silver Prism is the pinnacle of optical CD achievement and has been developed from the ground up for the highest run print systems; the Everest Prism and Screen/Litho printers.

Crucial in the development of this product has been not only our own expertise, but also our customers feedback, trials and comments – the River Media Pro CD-R Silver Prism is absolutely packed full of features that ensure smooth operation, unparalleled quality & consistency and best aesthetics.

With all of our new improvements, optimisation and our unrivaled development process, we’re able to produce one of the highest quality discs available today in the world and, additionally, one of the highest quality discs that has ever been produced.

The River Media Pro CD-R Silver Prism also incorporates the much lauded unique developments of other discs we’ve developed and manufactured, as well as new ones, such as:

    Anti-Sticky Surface:

    A common place on the majority of our manufactured media now (River-Media / ACU-Media), this specialist coating process ensures that discs remain separated from each other in storage and use, to eliminate problems with them ‘sticking’ together. It enables the discs to work smoothly with auto-loading machinery and ensures that runs are able to complete automatically, with no manual user intervention.

    Due to the easier handling and being less prone to errors, it also drastically increases the life of robotic machinery by up to 80%, reduces operator costs significantly and increases throughput!

    Reflectivity+:

    Reflectivity of optical media is crucial; it is how data is read back from the disc. Often discs with a clear coated surface, often referred to as uncoated, can show this easily as the disc can be show to be semi-transparent. It is harder to show with coated media, such as inkjet or thermal due to the extra layer, although the problem still exists.
    Not only is this aesthetically displeasing for an end user; but it also affects the accuracy of the playback of the disc and can additionally reduce the total working life of the disc by a considerable amount.

    With our Reflectivity+ technology, the reflective layer has been thickened and undergoes more stringent quality checks, even in raw material form, to ensure that the discs have exceptionally high reflectivity and will play back more accurately, as well as ensure a much longer life.

    EdgeReflect:

    A common problem automated duplication equipment has, especially in aging duplication machines or low-light environments, is difficulty reading internal sensors for locating and positioning media within them. This creates problems with double-loading and, essentially, machines falling over and being unable to continue production unless there is some manual intervention.
    It is quite common for the outer edge of some discs to thin slightly, due to the production process involved, which can cause a loss of reflectivity at the edges – which leads to sensor issues, as well as potentially some inner/outer-edge reading problems.

    With the EdgeReflect technology, we’re able to ensure a consistent reflective layer thickness, especially at the edge of the disc, aiding both playback and correct sensor tripping.

    Anti-Pit:

    It is easy to think that imperfections in a discs print surface aren’t common at all; however the majority of lower-grade media contains them, they’re just too small for the eye to see! While it is too small to aesthetically ruin the quality, these variations in the surface depth can wreak havoc with printing machinery and cause lower life for print heads, especially with direct-to-disc methods like the Everest Prism printer.

    By tightening the quality control checks on the disc surface and introducing a more accurate surface application, we’re able to reduce these minute problems significantly, giving you a considerably increased life on printing machinery.

The River Media Pro Silver Prism CD-R also only uses the highest quality, purest materials. Finest optical grade polycarbonate along with the strictest quality controls, even at raw-material level, ensures that these discs have the lowest error rates of any disc examined in the industry today.

With Taiyo Yuden’s exit from the market and stocks on core lines no longer available, it is certainly the time to seriously consider a high-quality alternative. With special introductory offers available, UK Warehousing for next day delivery and an unparalleled quality disc, get in touch today!

River Media, True A-Grade

Here at River Pro Audio, we’ve been manufacturing blank CD-R and blank DVD, optical media, for over 20 years. Optical media, although a mature technology, is still a complex method of storage and requires a high degree of technical skill, accuracy and experience to manufacture.

Here at River, we create all our optical media (blank CD-R, blank DVD and blank BDR) with the bottom line being quality, unlike other manufacturers who focus on price.

For the average consumer, so long as an optical disc burns it is generally considered good – however that could not be further from the truth.

Red Book Specification and Grading

The Red Book Specification governs the physical parameters and properties of a blank CD-R. Unfortunately, this specification is very broad, which enables factories to manufacture very poor quality blank CD-R and sell them alongside other, superior products with no legal distinction.

To combat this and highlight superior products several grading systems have been introduced, the most popular of which is a system from Clover Systems. You will often notice discs being sold as “A-Grade” or “AAA-Grade”, with reference to this system.

While well intentioned, this has only caused manufacturers to sell all their optical media as A-Grade; as there is no official, legal and enforced terminology of “A-Grade” media the majority of media making these claims are not “A-Grade”, by Clover Systems standard. This goes unnoticed by many consumers and professionals as they do not have the facilities to scan blank CD-R for defects.

River Media is true A-Grade. It has unparalleled reliability, consistency and archival length. It does this by offering:

No un-correctable errors

  • Un-correctable errors will cause audio artefacts, loss of quality, lower archival life and reduced playback compatibility

No E22, E32 errors (C2 / CU)

  • While it is possible in some modern players to correct these errors, earlier playback devices will be unable to. We consider E22 and E32 errors to be un-correctable in order to ensure the highest compatibility of our media with playback devices.

Exceptionally low BLER

  • Block Error Rate is defined as the number of data blocks per second that contain detectable errors.
  • Red Book Specification (IEC 908) calls for a maximum BLER of 220 per second (Average Over 10 seconds), which is a maximum of 2200 errors in a 10 second period.
  • River Media has an average BLER of 2.7, or 27 in a 10 second period; which is approximately 87 times higher quality than the Red Book Specification.

Why does this matter?

To an average consumer, so long as an optical disc works, it’s fine. However, to a supplier or producer of media, a disc that burns, or even plays is not the bottom line. Using lower quality media will result in returns and unhappy customers, costing time and money, as:

  • Higher error rates leave considerably less room for degradation, which negatively affects the resilience and archival life of the optical media. An optical disc with higher error rates may only be suitably read / played once or twice before they become unusable.
  • High error rates will reduce audio quality and produce audio artefacts, even if an optical disc plays fine when created, one with high error rates will see these problem manifest on different players and at an accelerated rate over time.
  • High error rates will severely reduce playback compatibility. While an optical disc may work with one reader, it doesn’t ensure it will work at all with another.

To prevent these problems occurring, we recommend using River Media products. Having the most consistent, low error rates of any media examined, you put yourself in the best position to serve your customers.

We’re so confident in the quality of our optical media and of our commitment to excellence that it is reinforced by our Unique, No Quibble, Satisfaction Guarantee.

We are proud to be the only optical media manufacturer in the world with this level of confidence in our products.
