![]() ![]() Conversely, multi-pole tape is multi polarity so it will be possible to stick multiple lengths together. This is because strips of single-pole tape will not be attracted to each other and each strip will repel the other. You must also ensure the tape is multi-pole rather than single-pole. Self-adhesive magnetic tape is recommended if you want to layer multiple strips of tape together. This will ultimately depend on the specific tape being used. Care should be exercised when using strong magnets near or with the tape - especially magnets stronger than the tape - as this could impact the tape's magnetic performance. It can also be used to stick materials together. The purpose of this tape is primarily to mount items to ferrous surfaces. For instance, if two pieces of the same type are placed on one another, each will repel the other. Magnetic tape is available in two forms - type A and type B. For example, 60cm² x 100g/ cm² = a maximum strength or pull force of 6,000g (6kg) Multiply this figure by its adhesive force per square centimetre. For example, a piece of 30cm long magnetic tape which is 2cm wide will have a surface area of 60cm Strength can be calculated using the following formula:Ĭalculate the surface area of the tape by multiplying the length by the breadth. This is a slow and laborious process in comparison to RAM (random access memory) which can be accessed in any order. ![]() It is a ‘serial’ access product, meaning that the reading device must fast-forward through the magnetic recording tape from the beginning to access a particular piece of data. It should also be noted that these kinds of storage devices have drawbacks as a data retrieval medium. Despite this impressive magnetic tape storage capacity, alternative storage mediums are often preferred nowadays due to the various limitations of magnetic media. To put that into context, modern desktop PC hard drives typically have a capacity of anything from 1 to 16 terabytes. In terms of magnetic tape capacity, up to fifteen terabytes of data can be stored on a single roll of tape. However, with the rise in popularity of cloud-based services, tasks like routine computer backups are becoming increasingly less likely to use a magnetic tape storage solution. This is because it is a capacious medium and therefore provides more storage space than alternatives like USB sticks and rewritable disk drives. However, it is still sometimes used as a medium for archiving, backups, and data storage. Magnetic tape in computer and secondary storage applications is being used less and less nowadays. Additionally, a different kind of magnetic tape was used as a method of storing large amounts of recording media such as video, audio, and computer code until the development of modern information technology.
