The Optical Industry – Powered By TY

Taiyo Yuden is a huge name in our industry; when you think CD-R, you think Taiyo Yuden. It’s an amazing example of an effective brand; but more than that, a stunning example of what a universal push for quality and technological advancement can achieve. This is something we here, at River Pro Audio, hold in exceptionally high regard as it is something we mirror with all our production and development.

Alongside Sony and Phillips, Taiyo Yuden pioneered the first CD-R, and associated technology, back in 1988 and their recordable discs were, and still are, considered to be amongst the very best in the industry; alongside our world-renowned ACU-Media and River Media brands (although they came much after!).

Unfortunately Taiyo Yuden no longer manufactures optical media, but they still exist as a highly respected manufacturer of high-quality electronic components and, to this day, continue their exemplary push for development and rigorous attention to detail.

With stocks of these impeccable discs running out, we here at River Pro Audio would like to extend our thanks to Taiyo Yuden’s remarkable technological achievements which made all things optical media related possible: from affordable, high quality music, to archival data storage and to the development of recordable DVD’s and Blu Rays.

One thing’s for certain, Taiyo Yuden discs may no longer be available, but their technology powers even the most humble of discs, and will forever.

Taiyo Yuden CD, DVD and BDR

Taiyo Yuden products are no longer in manufacture as of December 2015, please be aware of imitation Taiyo Yuden products.

With our large stock supplies we have continued to serve the quality driven Taiyo Yuden market, however we have increasingly seen a rise in Taiyo Yuden-like discs that are not performing to expected standards. Upon investigation of the media they, while using Taiyo Yuden MID’s in some cases, are discs manufactured post Taiyo Yuden closure and are not Taiyo Yuden media.

Taiyo Yuden are “working on eliminating imitation products”, but this is a difficult process, it’s recommended to be extra vigilant in your purchasing to avoid these products that can cause “quality failure”.

We will be marking Taiyo Yuden products that are no longer available with the above notice on our web store when they are no longer available from official distributors and recommending suitable, high quality alternatives to ensure your media production is not hindered.

Please contact us on 0208 311 7077 or sales@riverproaudio.co.uk if you would like to speak to one of our technical staff regarding your requirements, we will be happy to advise.

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.
