|Origin of Tape Drives|
The tape is an important part in the computer industry. This is the most type of the storage device. The tape is basically a magnetic storage device. The tape is used for the storage of the data. Presently the market has taken the space for the hard disk drives in contrast with the tape drives. The tape drives are there from at least half a century or so. The tapes where first used in the early 1950’s. The most important reason for the usage of the tape drive is cost effectiveness. It is much cheaper than the other storage media. Usually used for the back up or archival of the data. The capacity of the tape is much higher. And it still considered as the reliable efficient form of data storage. The storage system that was first implemented was on the reel to reel systems. This utilized the linear method of recording known as the serpentine. Later in the following years the open reel systems changed to the closed or single serpentine recording.
The tape systems are still used for the mainframe computers. The era in which the tape was launched belonged to the mainframe computers. Hence it was much widely used in the mainframe computer systems. The important reason for the usage of the tape is for the purpose of the data storage and backup. In the technique that was used for the recording of the tape that is the serpentine recording the data was written in the parallel tracks. The data was written in the bands that were alternating in nature. The bit density as well as the tape speed was increased in the later developmental stages. The open reel systems then lead to the invention of the tape that was called as the DLT Tape. The DLT Tape technology then leads to many features of increasing the features in the existing tapes. There was not much speed or reliability in the year of 1972; when the 3M introduced the concept of the QIC linear format that was eventually utilized for the purpose of storing the data. The data that was stored of such type of the disks was usually for the applications that are used for the acquisition of the data or for the applications that were used for the telecommunication of the data.
After the review of all these things; in the year of the 1987 a new conceptual drive that was based on the helical scan was introduced. The Exabyte was responsible for the introduction of the technology. This was considered of having a high rated performance as in comparison with the existing tape drives at that time. There were many features that were present in the tape drive like the data verification in the sense of ‘read after write’, high retrieval system and also it had the data integrity. The feature like the data integrity that is included in the tape drive provides the required integrity for the data storage. The physical specifications of the helical scan drive were about 8 millimeter. Later in the year of 1996 the Exabyte again launched a new feature that is popularly called as the Mammoth Tape Technology. More over the company made remarkable progress in the tape technology with the introduction of the M2 tape drive in 1999 and Smart Clean media in the year of 2000.
