IBM 305 RAMAC The IBM 305 RAMAC was the first commercial computer that used a moving-head hard disk drive for secondary storage. The system was publicly announced on September 14, 1956, with test units already installed at the U.S. Navy and at private corporations. RAMAC stood for Random Access Method of Accounting and Control, as its design was motivated by the need for real-time accounting in business.

- Microsoft Windows Server 2003 supports the file allocation table (FAT) file system on basic disks and on readable/writable disks. Basic disks and volumes are the storage types most often used with Windows operating systems. During the format of a volume, you can choose the type of file system for the volume.

JUST THE FACTS Answer     The digital compact disc, now commonplace in stereos and computers, was invented in the late 1960s by James T. Russell.     The first floppy was mad…e by IBM around 1970 (this was an 8 floppy). The 5 1/4 floppy was introduced in 1976 and Sony pioneered the 3 1/2 floppy with a hard shell in 1981.

Manchester Mark I Williams-Kilburn tube The tube, tested in 1947, was the first high-speed, entirely electronic memory. It used a cathode ray tube (similar to an analog TV picture tube) to store bits as dots on the screen’s surface. Each dot lasted a fraction of a second before fading so the information was constantly refreshed.

Magnetic Storage: Definition, Devices & Examples Types of Magnetic Storage Devices. Magnetic tape is one of the older types of magnetic storage media. The magnetic tape recorder was invented in 1928 and was primarily used for analog audio recordings. Before music CDs were introduced in the 1980s, portable music devices used magnetic tape in the form of music cassettes.

Jan's Computer Basics: Types of Magnetic Disks. Hard Disks. A hard disk consists of 1 or more metal platters which are sealed inside a case. The metal is one which is magnetic. The hard disk is usually installed inside the computer's case, though there are removable and cartridge types, also. Technically the hard drive is what controls the motion of the hard disks which contain the data. But most people use hard disk and hard drive interchangeably.

- Computer can store files on the disk (secondary storage), for long term storage purpose. Few examples of storage media are magnetic tape, magnetic disk and optical disk drives like CD, DVD. Each of these media has its own properties like speed, capacity, data transfer rate and data access methods.

What Is the Difference Between Optical & Magnetic Storage? Magnetic storage devices use read/write heads, electromagnets that detect (read) or change (write) the magnetization patterns on the disk. Optical storage devices use lasers to read the reflections in the disk or burn the data pattern into the disks.

Computer Basics: How Is Electronic Data Stored on a Computer or Mobile Device? Magnetic storage is commonly used on the hard disc drives found on most computers. Information is stored using positive and negative magnetic charges to correspond with the 1s and 0s noted above. Optical discs like CDs and DVDs store information as binary code that can be read by an optical sensor in a disc drive.

- Throughout the first decade of the 20th century, developments in disc technology bring to light the inferiority of the cylinder playback technology. In 1901, the 78 debuts. Named for its rotational speed of 78 rotations per minute (rpm), the 78 is 10 inches in diameter and lasts as a format until 1974.
