HISTORY AND DEVELOPMENT HARDDISK

                       HISTORY AND DEVELOPMENT HARDDISK

Hard Disk Drive or often referred to as 'drive alone' is one component

important in the computer. Hard Disk Drive has another name, which is generally called recording media that serves to store data (information). Many of us are using the hard drive, but probably very few people know the origin of the Hard Disk Drive. Therefore, in this forum I tried to discuss the origin of the hard drive first.

Hard Disk Drive first created and produced by the IBM company in 1956 which was later named as the first-generation HDD. The first HDD was invented and created by Reynold Johnson. HDD is labeled RAMAC 305 which has a capacity of 5 Mega Bits or five million bits and measuring 24 INCH and menggunakkan single head in access

In 1961, IBM created the HDD with a separate head menggunakkan in each component data. Also called Disk Storage Unit Control System Meganical International System. And the first HDD to removable (can be removed or installed again) is an IBM 1311, IBM 1316 that use to store 2 million characters.

In 1973, IBM introduced the IBM 3340, the first to use the HDD merupakkan system disk "Whincester", the first using a sealed head / disk assembly (HDA). This technology is designed by Kenneth Haughton.

Before the 1980's, HDD kebanyakkan berurukuran 8 INCH or 14 INCH, so it requires a lot of space to store the HDD. Until 1980, when Seagate ST-506 mengenalakan technology which is the first HDD-sized 5.25 inch with a capacity of 5 megabites.

And even now, the HDD has reached capasita Terrabites 3.5 inch in size, for those following me that I can provide a timeline of the web on the development of the HDD to date.
