Transcript of Invention of Hard Disk Drives

What is A Hard Disk Drive?
A Hard Disk Drive (HDD) is a high-capacity, self-contained storage device containing a read-write mechanism plus one or more hard disks, inside a sealed unit. Also called hard disk drive.
What Need Did Hard Disk Drives Address?
Hard Disk Drives allowed people to store all kinds of data, programs, and softwares onto computer for easy access. They used to hold small amounts of data, at first only holding 5 Gigabytes (GB) and the HDD would be really large in physical size. Now, an HDD can hold over 1 Terabyte (TB) of data, while being fairly small in physical size.
Who Invented The Hard Disk Drive?
The HDD was invented by the International Business Machines Corporation (IBM) on September 13, 1956. The company's headquarters are in Armonk, New York. It was put in their 'SUPER' computer, the 305 RAMAC.
Improvements to the Hard Disk Drive
Over the years, Hard Disk Drives have become very small, but still hold a lot of data. HDDs used to weigh over a ton and be over 24 inches with only 5 MB of storage. Now, HDDs are very light weight and small, being no bigge than 5 inches. They could how aS much as 2 Terabytes of storage.
Invention of The Hard Disk Drive
Why were the Improvements Made?
The improvements to the Hard Disk Drive were made in order to be more transportable, and to hold more data for faster data processing, and faster usage of stored data on the HDD
When Was The First HDD Created?
The first hard disk drive was created on September 13, 1956 by IBM. It was when they lauched the 305 RAMAC, known to be the first "SUPER" computer with a hard disk drive. The HDD weighed over a ton and held 5 Megabytes (MB) of data and costed $10,000 per Megabyte.
Patents on The Hard Disk Drive
There is a 1970 US Patent (3,503,060). It was the first patent on the RAMAC program, and was fundamental for all hard disk drives. It is the earliest known patent that has claims that cover all modern disk drives today.
Original Materials for Hard Disk Drives
Hard Disk Drives have one or more platters using a magnetic head to write data, of which is all inside an air-sealed casing. Then platters are made of aluminum, but some are made of metal coated glass.
How Hard Disk Drives Were Originally Made
Al Shugart, former field engineer at IBM, was stated to have created the hard disk drive scratch. Electrical and mechanical engineering would have had to been put to use to make a Hard Disk Drive, as it has some moving parts on the inner workings of it, and uses electrical signals to communicate the data it stores with the rest of the computer the HDD may be inside of.
Who Uses Hard Disk Drives?
Anyone who uses a computer in any sort of way, is using the HDD as well. All data on a computer is stored onto the HDD, and one will always constantly be storing data to the HDD, as well as open data from it. Most things done on a computer are also temporarily stored onto the HDD using Random Access Memory (RAM). This is what causes the simple use of a computer become the use of an HDD.
Global Impact of Hard Disk Drives on Society
Hard Disk Drives have had a good impact on society on a global scale. For one, they were the only way for corporations to store large amounts of data before cloud systems came, and are still the main form used today. HDDs also revolutionized the usage of computers, in terms of them getting smaller over time, and holding large amounts of data, allowing people to have easy access to things they may have created.

One Thing To Change About Hard Disk Drives
One thing I'd change about Hard Disk Drives is the range of devices they are used on. HDDs are meant for computers and laptops for the most part, but are not used on many, if not any small devices. Although smaller devices (such as tablets and phones) have a Solid State Drive (SSD), they don't hold as much space as an HDD can. It would be much better for these devices to have such drives, as sometimes SSDs may not provide enough space. However, phones and tablets would become much more expensive by a large amount if one were to fit an HDD in there.
