The Tape Drive
Multiple tape cartridges are used in conjunction with automated media processing equipment for the data storage and transfers. Over 80 percent of the world’s digital data is stored on tape. Tape drives can be said to be the central technology in all disaster protection architecture. Important tape in disaster prevention, and to restore growth.
Start: tape drive has been more than five years of the Decade. It has its own scaled new heights in the ever-changing technology. Ibm company invented the tape, in 1960 as a multi-purpose, bulky storage device. The invention of the tape early, can be divided into three periods:
– I bm section 1 360p hotostore period, from 2 0 century 6 0’s
1 ibm company in 2321 data cells period from the mid-1960s
– Grumman m asstape period from the late 1 960s/early 1970s
Various forms of the tape, including scroll, chips, belt, gas cylinders and film products. These tapes form, characterized by access time of less than 10 seconds and capacity over 3.1 hours. However, the bulky size and the unreliability and high maintenance costs and restricted the tape’s popularity in the 1970s. This changed in 1988. Soragetek invention acs4400 tape library. This modification does not exist tape drive. Tapes become the Asia-Pacific media data storage and backup. It began to be widely used in commercial enterprises and individual users.
Features:
– With tape, including 8 mm e xabytev xa, Sony AIT Taipei Office, d lt lt and the super d l tou ltrium, i bm compatible half-inch 3 490 cartridges, s toragetek of 9 940 points 9840 and Sony salt.
– Tape the use of a sequential method of reading data or information access.
– Reliable and durable
– Physically strong and the internal structure of strong magnetic field
Data loss: modern tape technology, exposed some structural weaknesses. This makes them much easier to data loss.
Magnetic internal cavity: tapes may appear to be strong physically. Internal disk cavity is sensitive magnetic field. Therefore, tapes and require high maintenance. Lead improper care coverage. Therefore, a large number of data loss. Therefore, users must take certain health maintenance Note:
– To avoid traveling to the tape. Even if you were cumbersome procedures to ensure it is protected. Tapes must be wrapped in a protective sheath. It is closed, in terms of organization or plastic.
– Users with no holidays tape. Struggles, and throwing from the highly should be avoided.
• The tape should not be exposed too much light, heat and humidity. This may result in internal damage and lead to data loss. Users should maintain the tape in cold regions.
• The tape should stay away from pets.
• The tape should not deal with oily and greasy fingers.
– In most cases, the video should be kept in a vertical position, to love abrasions and cans.
Power Surge: tapes is intricate and complex data storage equipment. Users must ensure that all the connections are correct. The tapes have been kept in a compatible driver, in order to avoid the ESD. Users must ensure that all the connections are closely disconnect.
Natural and man-made disasters: the tape is prone to corruption and data loss through natural disasters, floods, fires and earthquakes. At best, users can also use tape backup of large memory capacity. The tapes can be stored in the secondary site be kept away from natural disasters.
Man-made disasters data theft and terrorism plague tapes more than any other data storage devices. Tapes are often recovery loans, their data intrusion. Very cheap, but the price is usually in the data. Tapes, not any kind of internal security. This makes them much easier to target data being pilfered.
Advantages
Capacity: tapes boast of extremely large storage options. Tape drives can store more than 50 gb of data. They are used as a major Asia-Pacific backup media. They provide off-line storage options.
Cost: Tape cheaper. Individual users have the ability to appropriate and reliable backup of several bytes of data at a cheaper rate. It has a low market prices. The tape, cheap backup allows users to the program.
Reliability: Tape is reliable and durable. It continued to operate for a short time after the tape’s internal affairs directorate failed. This allows users to store data before all the tapes corruption. Its structure to withstand shocks and physical coercion. With proper maintenance, tape function can be for a long time.
Simple and universality: the tape is convenient and easy to use. They do not need the technical knowledge. Portable tape. They are used to optimize the automated tape library.
