The key word is changing.A changing current produces a changing magnetic field, which randomizes the previous magnetization of tape. Strong Changing Current -> Induced Magnetic Field -> Randomize Tape Magnetism

With the exception of our 20 mm wide Magnetic Tapes (which are self-pairing), you will need both A & B rolls if you wish for the magnets to attract to each other, if you're simply looking for the magnetic tape to attract to other steel / ferrous based surfaces then it doesn't matter if you use A, B or Self pairing as these magnetic tapes are all attracted to these surfaces. What is Magnetic Tape? Alternatively if you want to use both A & B sides of the tape follow the same procedure with the exception of using the A or B side to secure an object to the tape. Make sure that both the A & the B side are aligned with each other so that the tape works as effectively as possible. While good for short-term use, magnetic tape is highly prone to disintegration. Depending on the environment, this process may begin after 10–20 years. [1] Magnetic tape storage is also well-suited for archiving because of its durability, as it generally has a 30-year shelf life. Tapes are also easily movable, while disks are not as portable. In a disaster recovery scenario, as long as the tapes are far enough away from the affected data center, an organization can use them for restoration.The basic principle behind the working mechanism remains the same for all magnetic tapes, irrespective of the year of manufacture. As materials science has advanced, tapes with suitable physical and chemical properties such as thin width, high flexibility, high data density, and resistance to humidity, were developed in the latter half of the twentieth century. When disk and its random access hit the market, it largely replaced tape for primary storage. Some industries, though, such as media and entertainment, as well as sciences and video surveillance, heavily use magnetic tape for storage, notably for its large capacity. The tape keeps moving and the successive patterns of magnetization produce a corresponding audio output.
In terms of magnetic tape capacity, up to fifteen terabytes of data can be stored on a single roll of tape. To put that into context, modern desktop PC hard drives typically have a capacity of anything from 1 to 16 terabytes. Despite this impressive magnetic tape storage capacity, alternative storage mediums are often preferred nowadays due to the various limitations of magnetic media. This makes magnet tape perfect for industries such as retail and manufacturing but can also be used domestically for DIY projects. How to use Magnet Tape Magnetic Materials" (PDF). Memory of the World: Safeguarding the Documentary Heritage. A guide to Standards, Recommended Practices and Reference Literature Related to the Preservation of Documents of All Kinds. UNESCO. 1998. CII.98/WS/4 . Retrieved 12 December 2017. The top coat (magnetic emulsion) of the tape is fed to the write-head. The wire wound around the write-head carries the electrical signature (current) of the sound to be recorded. The current-carrying wire induces a proportional magnetic field M. Magnetic tape is the low-cost average for storage because it can save a huge number of binary digits, bytes, or frames on each inch of the tape. The benefit of magnetic tape contains unconditional storage, inexpensive, high data density, fast transfer rate, flexibility, and ease of use.

Access Time− Accessing a record requires accessing all the records before the required record. So access time is very large in magnetic tape. Our magnetic adhesive tape is a flexible and reliable product that comes in a variety of sizes and has both the A & B side included. The strong adhesive of magnetic tape binds to surfaces creating a strong seal so that it won't be removed easily. We also have a variety of adhesives to choose from as well with a choice of strong, standard and foam adhesives. This also creates a viable alternative to just using adhesive tape. Modern magnetic tape storage traces its roots to the 1950s. When the first modern commercial computer, the UNIVAC I, was released in 1951, the inventors used magnetic tape to supplement the computer's storage, according to data storage vendor Iron Mountain. Calculate the surface area of the tape by multiplying the length by the breadth. For example, a piece of 30cm long magnetic tape which is 2cm wide will have a surface area of 60cmAs mentioned previously there are many ways in which to use magnet tape. For example, you could use magnet tape for securing: A current-carrying wire produces a magnetic field around itself, with the field lines being closed circles. Tape libraries had a boom in the mainframe era when large computer systems ran compute jobs in groups. Operators stored a program and its data on tape, moving the job off the computer for temporary storage and reloading it when it needed to be run again. Multiply this figure by its adhesive force per square centimetre. For example, 60cm² x 100g/ cm² = a maximum strength or pull force of 6,000g (6kg) The tape is now magnetized. The magnetization of the pigments is proportional to the external field M, which itself is a signature of the input current, which is a signature of the original input audio. Audio -> Electrical Signal (Current) -> Induced Magnetic Field M-> Magnetization of Tape
The top coat consists of a magnetic pigment held together by a binder to form an emulsion. The magnetic pigment consists of a ferromagnetic substance like ferrous oxide, chromium dioxide or pure iron. The pigment provides small magnetic domains that can be manipulated to create and store signals. The binder is a thermoplastic polymer like cellulose acetate or polyurethane, which has the magnetic pigment pigments embedded in it. The top coat is quite thin and ranges from 2um-13um in cross-sectional length.

In 1900, magnetic recording on wire was introduced by Valdemaar Poulsen, a Danish engineer, for exhibition at the World Fair in Paris. In 1928, magnetic tape was introduced in Germany to record and store audio. Ferromagnetism: Some elements are strongly attracted to external magnetic fields and get permanently magnetized when exposed to external magnetic fields. Such elements are called ferromagnets, and this phenomena is called ferromagnetism. Ferromagnets consist of thousands of microscopic regions of uniform magnetic fields called domains. Each domain’s field has a net magnitude and direction. If a sufficiently strong external magnetic field is applied, all the domains align themselves along the direction of the external magnetic field to reach the lowest energy state.
