The tape causes memory killing, how should the tape fold be repaired?

As a memory of my childhood, the tape is full of memories. Although mobile phones and computers are more convenient, and no one uses tapes now, there must be some tapes collected in the past. In the process of use, the magnetic tape often breaks and folds because of its deformation, which further affects the operation of the magnetic tape or the effect of recording and playing sound. Therefore, you need to iron it before you can continue to use it. Just put the fold on a 40-watt white light bulb, and then slowly pull the fold left and right with both hands, you can remove the fold and reuse it.

If you want to repair the folds of tape, the most important thing is that you know what tape is. Magnetic tape is a kind of magnetic tape material with magnetic layer, which is used to record sound, image, digital or other signals. It is usually formed by coating a layer of granular magnetic material on the base of plastic film, or depositing a layer of magnetic oxide or alloy film by evaporation. Paper and celluloid used to be the base materials of adhesive tapes, but now polyester films with high strength, good stability and no deformation are mainly used.

In today's society, magnetic tape has been gradually eliminated in life, but in fact, there are still a lot of data stored by magnetic tape, including basic scientific data, such as particle physics and radio astronomy, as well as human cultural heritage, national archives, important movies, banking, insurance, oil exploration and other data, and a group of people are looking for ways to improve the storage capacity of magnetic tape.

In essence, compared with hard disks and semiconductor storage devices, the access speed of magnetic tape is really much slower. However, as a storage medium, magnetic tape still has many advantages. First of all, tape is very energy-saving. Once the data is recorded by tape, it will be put into the tape library and then lie quietly without consuming any energy. Secondly, the tape is quite stable, and the error probability is 4-5 orders of magnitude lower than other storage devices.
