A Brief Guide to Blu-Ray Discs and The Different Kinds of Format

There’s more to Blu-ray discs than meets the eye, and there are various things you should take note of before purchasing them. Blu-ray discs are starting to rise since they store more data than compact discs, such as CDs and DVDs. But, you also have to consider the different types of Blu-ray discs so that you can make the most out of them.

When it comes to storing your old video and audio files, you may find CDs and DVDs more convenient since they’re slightly cheaper compared to Blu-ray discs. However, CDs and DVDs may become problematic for those expecting their old video and audio files to retain their quality.

Blu-ray enhances the quality of your old video and audio files, making them feel and look up-to-date. It would be best if you also took note that there are different types of Blu-ray discs before purchasing them to prevent future errors and confusion. With that in mind, here is a brief guide to Blu-ray discs and the different kinds of format.

Types of Blu-Ray Discs

Categorizing the Blu-ray discs is vital to understanding how they work. Consequently, there are two types of Blu-ray discs, mainly writable and rewritable. Familiarizing yourself with the kind of blu ray disc you’ll be buying is essential since you can only write on the disc once while rewritable means you can add or remove data.

Aside from the two basic types of Blu-ray discs, here are the different format types that you should keep in mind before buying them.


Blu-ray disc recordable or BD-R is a type of format where you can only record data onto the disc once. Moreover, BD-R discs can have up to four layers, which significantly impacts how much data they can store. The single layer can store up to 25Gb of data, the double layer can store up to 50GB, the triple-layer can store up to 100GB, and the four layers can store up to 128gb of data.


Blu-ray disc rewritable or BD-R is a high-resolution storage format where you can erase and rewrite data. Similar to the BD-R format, the storage capacity will depend on the number of layers that the disc has when you purchase them.


Blu-ray disc extra-large or BDXL means that you have extra-large storage capacity. The BD-XL format can either be writable or rewritable, wherein the size of the storage capacity may differ depending on the type of disc. The writable type can have up to 128GB of storage capacity while the rewritable only has 100GB of maximum storage capacity.

Ultra HD

The Ultra HD format is the higher version of the other disc formats since they provide you with improved video quality for all your stored videos. Further, the high-efficiency video coding technology that comes with the Ultra HD format processes images for up to 60 frames per second. For short, you can play 4K UHD videos in this Blu-ray disc format.

The advantage of the Ultra HD Blu-ray is that it can process and deliver information rapidly without the need for an internet connection.

Takeaway of discs

Knowing the two basic types of Blu-ray discs and the different formats they come with can help you decide which disc suits your needs. Apart from their formats, you should also take note of their layers since they determine the Blu-ray disc’s maximum storage capacity.
