Yes, a Blu-ray disc holds more data than a DVD. A single-layer Blu-ray disc can hold up to 25GB of data, while a dual-layer Blu-ray disc can hold up to 50GB. In comparison, a single-layer DVD can hold up to 4.7GB of data, and a dual-layer DVD can hold up to 8.5GB. This increased storage capacity allows for higher quality video and audio on Blu-ray discs compared to DVDs.
The disk size is defined by the manufacturer. You can't store more information than the disk can hold, just like you can't store more water in a jar that it can hold.
Disc drives can hold more data than catridge drives.
Because a CD was designed to hold more data.
Absolutely. Most DVDs hold less than 5gb of data (dual layers less than 9gb) while hard discs today can hold many terabytes of data.
Could be nothing more than the Bluray DVD's that you're watching aren't encoded in 5.1 surround.
A DVD player is a better decision than a BluRay player based on price alone. This type of player is cheaper. A BluRay player may be a better idea because it can also play DVDs and has more advanced features.
Blu-Rays can hold up to a maximum of 50GB, which is 5 times more data than a DVD can hold
CDs and DVDs share the same physical format but the DVD stores more data that a CD. It does this a much finer set of optical tracks on the disc than the CD has. In a similar way, Bluray discs hold far more data than a DVD.
3.5" and 5.25" were available in a variety of capacities. 3.5" disks maxed out at 2.88 MB, while 5.25" topped out at 1.2 MB. It is quite possible for a 5.25" disk to hold more data than some 3.5" disks.
No, a floppy disk is not bigger than a SuperDisk. A standard 3.5-inch floppy disk typically has a storage capacity of 1.44 MB, while a SuperDisk, which is often 3.5 inches in size but designed to hold more data, can store up to 120 MB or more. Therefore, in terms of storage capacity, the SuperDisk far exceeds that of a standard floppy disk.
A Standard CD is 700MB whereas a single layer bluray is 25GB, doubled to 50GB for a dual layer, 100Gb for a triple layer and even 128Gb for a quadruple layer disk.
A Bluray disc stores five times more data than a DVD. Therefore, a DVD will not have the capacity to store the contents of a Bluray disc.
