The opposite day, as I used to be perusing by means of my disc binder assortment of Blu-rays and DVDs, I had an epiphany: if two is healthier than one, then, by extension, a dual-sided optical disc is definitely higher than a single-sided disc. In any case, vinyl information and cassette tapes make use of double-sided storage expertise, and so why not lengthen the idea to optical-based media as properly?
A fast Google search later, and I discovered that I used to be removed from the primary particular person to conceptualize a next-generation double-decker optical disc format. In reality, a bunch of document firms went by means of the difficulty of researching and creating exactly such a format within the early 2000s, they usually known as it DualDisc.
DualDisc was first launched to the general public in 2004, having been co-created by MJJ Productions Inc, EMI Music, Common Music Group, Sony BMG Music Leisure, Warner Music Group, and 5.1 Leisure Group, with added backing from the Recording Business Affiliation of America (RIAA).
Document firms reckoned that the format may supersede CDs.
The DualDisc format featured a normal audio CD on one aspect, with a video DVD on the opposite. Whereas not the one dual-sided optical media format to have hit retailer cabinets (different codecs like DVDplus have been developed independently), DualDisc was distinct in that it had mighty institutional backing.
Document firms reckoned that the format may supersede CDs for the distribution of music, whereas additionally decreasing the prevalence of piracy by prioritizing reasonably priced and unique bonus supplies at no further price to the buyer. These firms collectively wager massive on DualDisc for a short time frame, even going so far as to launch sure albums completely on the format.
Double the readable surfaces, double the difficulty
The DualDisc format got here with professionals and cons
On the floor, DualDisc seems like a no brainer evolution of present optical disc applied sciences. The power to play audio on one aspect and to then watch movies on the opposite is undoubtedly compelling on each a conceptual and a practical stage. Plus, a devoted participant is not essential as a consequence of piggybacking off of present CD and DVD applied sciences. Even nonetheless, the format suffered from some roadblocks proper from the beginning.
A single DualDisc measures in at 0.06-inches (1.5mm) thick, which is ever-so-slightly thicker than a normal CD, DVD, or Blu-ray at 0.05-inches (1.2mm). As such, DualDiscs expertise issues when inserted into sure slot-loading disc drive mechanisms. DualDisc’s CD layer additionally would not conform with the Purple Guide specs of the CD format, which means that it confronted the hurdle of Philips and Sony not sanctioning the format.

However, DualDisc is a really cool optical media format on the entire. The CD aspect of the equation is good for 16-bit audio sampled at 44.1kHz (normal CD high quality), whereas the DVD aspect is able to offering 24-bit DVD-Audio at varied pattern charges. The DVD aspect may feasibly include the identical album in increased constancy and with encompass sound, or it may maintain corresponding music movies, hyperlinks to web sites and different sources, and even full-fledged movie.
Sadly sufficient, DualDisc suffered an premature demise. The format was sundown in 2007, immediately being relegated to the realm of collectors and audiovisual aficionados. I do wonder if the thickness challenge is one thing that would have been overcome with immediately’s extra fashionable applied sciences, in addition to whether or not costs would’ve come down had the format remained on retailer cabinets for only a bit longer. Alas, it merely wasn’t meant to be — DualDisc by no means reached the astronomical heights of its single-sided CD and DVD contemporaries, and that is a real disgrace.
