.... the tape, control tape reeling, guide the tape to maintain its position relative to the heads, control the acceleration and steady state velocity of the tape, and control tape tension [66] The substrate for magnetic tapes is a poly ethylene terepthalate (PET) base film from 12 to 36 microns thick [13]. There is a tradeoff between reliability and capacity in choosing the thickness of the substrate. A thicker substrate is more durable and able to withstand high accelerations and start and stop operations without excessive distortions [66] A thinner substrate allows a single reel to store more ....
....thin film tapes hold greater capacity. In addition, thin film media have recording characteristics superior to those of particulate media, including higher effective magnetization, lower error rates, greater smoothness, highly isolated asperities, and better signal to noise ratios [59] 82] [13]. Besides the plastic substrate and the magnetic coating, most magnetic tapes have a back coating for protection against static. Electrostatic attraction can lure and embed dust particles from the atmosphere into the tape, causing read and write errors. Figures 2.1 and 2.2 show the two most common ....

....However, some errors will occur that the ECC cannot correct. The rate of such errors is typically in the range of one in every 10 12 bits read to one in every 10 15 bits read. Magnetic tapes that are frequently read or written eventually wear out. Tapes last on average several hundred passes [3], 22] 25] Wear due to frequent stops and starts on the tape can be particularly severe. Another set of reliability concerns involves the long term storage of data on tape. Over time, tapes are subject to corrosion and to mechanical changes including tape shrinkage, creasing of the edges, ....

....incorporate large amounts of error correction code. Despite this, tapes occasionally encounter errors that cannot be rectified by the ECC. Tape wear is another reliability issue. Magnetic tapes that are frequently read or written eventually wear out. Tapes last on average several hundred passes [2], 12] 16] However, they wear out sooner if a particular segment of the tape is accessed repeatedly. Frequent stops and starts on the tape cause excessive wear. Tape heads also wear out, typically after a few hundred or thousand hours of use. Another set of reliability concerns involves the ....
