I’m a big fan of optical-based media. Despite having a reputation for being slow, clunky, scratch-prone, and outdated, there are very clear merits to optical-based storage that make for a worthy storage medium on the whole.
Now, for the most part, mainstream optical media formats like CDs, DVDs, and Blu-rays are uniform in size, measuring in at a diameter of 4.7-inches (12 cm). Lesser known is that DVDs and Blu-rays also come in smaller-scale Mini flavors, both of which feature 3.1-inches (8 cm) diameters.
In the case of Mini Blu-ray, a single-layer disc can store approximately 7.5 to 7.8 GB of storage, while a dual-layer disc can achieve up to 15.6 GB of total capacity. There are even recordable (BD-R) and rewritable (BD-RW) Mini Blu-ray disc variants, which supplement the read-only standard discs.
The Mini Blu-ray disc format deserved better
Disappointingly, the optical disc standard never took off
In all likelihood, you’ve probably never come across a Mini Blu-ray disc in real life. The unfortunate reality of the situation is that the standard has suffered an untimely death, having been relegated to the realm of tech that never took off.
There are a variety of reasons why this is the case, most notably relating to their lesser storage capacity when compared to a standard Blu-ray disc. I reckon there was a chicken-and-egg situation that played out, where there weren’t enough mini Blu-ray discs circulating to justify mass-producing Mini Blu-ray players, and there weren’t enough players to justify pumping out Mini discs.
Ultimately, while there were a couple of Mini Blu-ray camcorders that hit the market in the late 2000s, these products fizzled away without much fanfare. Today, the standard has become obscure to the point where it’s nearly impossible to even purchase blank discs (trust me, I’ve tried).
…I’d personally love to see a mini Blu-ray disc renaissance take place.
This is all a really unfortunate reality, as Mini Blu-ray is a genuinely cool format. I love the miniature dimensions of the discs themselves, and their maximum storage capacity is significantly higher than, say, a full-sized DVD. I can imagine an alternative reality in which triple-layer discs emerged onto the scene, which may have theoretically reached 25GB or even higher.
Optical discs themselves are experiencing a comeback of sorts, and I’d personally love to see a mini Blu-ray disc renaissance take place. I’m bullish on Blu-ray’s potential as a CD successor for music distribution, and the diminutive dimensions of Mini BD make for an ideal candidate thanks to the sheer compactness and convenience that comes with the territory.
