Like DVDs, Blu-Rays are double-layered and a double-layered Blu-Ray disc can hold up to a maximum of 50 GB, which is 5 times more data than a double-layered DVD can hold

What is harddisk and how many types of harddisk are there?
A hard disk is what all your files, including the Operating System are stored in. There are many sizes of hard disk and what the capacity is.
How many CD should be used to save data in a Blu-ray disk?
A commercial Blu-Ray disk (i.e. a movie) has a capacity of 50 Gb.A CD has a capacity of 650 Mb, a DVD (single density) has 4.7 Gb and a DVD-DL has 8.5 GbSo one Blu-Ray disk would require 6 DVD-DL disks, 11 single-layer DVDs, or 77 CDs for an equivalent amount of storage.With that said, most disks are not filled to 100% capacity with programming/ content, so fewer disks may be required. But then, dividing up a large disk into smaller portions also requires some overhead (each disk requires certain formatting and directory structures), which could increase the number of disks.

How many megabytes has a floppy disk?
The capacity of a disk depends on its type. You're probably thinking about a standard 3½" floppy disk. It holds 1440*1024 bytes, which equals 1474560 bytes. For other capacities, look below
What is the maximum storage on DVD?
It depends on the disc you buy and it should say how many minutes it can hold. There are many kinds of DVDs with varying capacities. Single layer, double layer, single sided, double sided... Printed on the disk (CD or DVD) there will be a number listing the capacity of that disk - DO NOT BELIEVE IT. The practical storage capacity of the disk is about 93% of that number. You are safe in assuming 10% of that printed number should be lopped off giving you a practical storage capacity. So, a DVD-5 (single sided, single layer, 12cm diameter (regular sized DVD)) says it holds 4.7GB. In practical application that disk actually holds about 4.38GB. WHY? Well, the GB listed there is base 10 (SI units) in that a kilo = 1,000, where in practical computer terms, Kilo-byte, a binary number, is 1,024. That little 24 over 4.x GB adds up making the practical storage of any digital medium about 93% of the base 10 storage capacity printed on the front. Why don't manufacturers list the practical storage capacity instead of the base 10 number? I don't know. Maybe bigger is better? If company A lists a DVD at 4.7GB and company B lists the exact same DVD as 4.38GB, which one would you buy? Even though they store exactly the same amount, consumers want more for their dollar.
Factors enabling a DVD to reach 17GB?
Thanks to improvements in optical laser precision many DVDs today are dual-layer, meaning that there are tracks within the normal spaced tracks, effectively doubling the storage size to 8.5GB. When you hear of a 17GB drive this is essentially a dual-layer DVD that has been written on both sides (top and bottom). While this eliminates having printed art on one side of the disk, it does allow for twice the data capacity as as a normal dual-layer DVD.
What stereo system has the largest CD library capacity?
If you are looking for a stereo system that has a large CD library capacity you should go with a player that has a multi disk option .Sony and Yamaha are both great brands and also come with disk options for up to as many as 10 CD's , which you can even find for a great prices if you shop around .
What did Alan chugar and IBM invent in 1970?
If you mean Alan Shugart, then it was the floppy disk. An 8 inch inexpensive disk with a capacity of 80,000 bytes used for loading System/370 microcode.A few years later Alan left IBM to start his own floppy company, making many improvements both increasing storage capacity and reducing size.
What is the largest capacity hard disk drive that is commercially available?
The largest capacity hard disk drive that is commercially available is four terabytes. It can be purchased at many websites online, as the internet is filled with a variety of options, giving the buyer numerous choices.
What is the capacity of the floppy disks?
The most common ones most people are familiar with were 1.44MB, but there were many sizes of "floppy disk" from about a hundred kilobytes to a couple hundred megabytes. Nowadays, the answer is 1.44 for a double sided high density 3.5" floppy disk. This answer is quite different for other types of floppy disks. There are single sided, double sided, single density, double density, high density , 5.25", 3.5", and 8" floppy disks just to name a few of the many, MANY variations. * low density capacity: 360 kbytes * hi density capacity : 720 kbytes * double hi density: 1.44 megabytes There are other (rare) formats that can hold more.
Why optical disk is not used in hard disk?
Optical disks are defined as "Write Once/Read Many" media. Some optical disk can be re-written. This is accomplished by burning the first layer smooth and writing the bit bubbles again. This can only happen a few times before the optical media is spent. Magnetic disks are defined as "Write Many/Read Many" media. This is what is needed for the continued operation of a computer over any extended duration.
What is the largest capacity of disk space that can be installed in a QNAP NAS device?
Many of these type devices allow for multiple disk drives so the available space is almost unlimited. There are systems with 10TB drives but Seagate claims NAS devices can only handle up to 4 TB.
