Computer storage tape media, often simply referred to as tape storage, is a type of data storage technology that involves the use of magnetic tape to store digital information. This medium has been used since the early days of computing and remains relevant today for specific applications. Here are some key points about computer storage tape media: ### Characteristics: 1. **Magnetic Tape**: Tape media consists of a long, narrow strip of plastic film coated with a magnetizable material.

A glossary of backup terms is a collection of definitions and explanations of key concepts, terminology, and jargon commonly used in the context of data backup and recovery. Understanding these terms can help individuals and organizations effectively manage their data and implement robust backup strategies. Below is a glossary of some important backup-related terms: ### A - **Archiving**: The process of moving data that is not regularly accessed to a separate storage location for long-term retention.

The IBM 7340 is a model of a magnetic tape drive that was part of IBM's line of storage devices. It was designed for use with IBM mainframe computers and other compatible systems during the mid-20th century. The IBM 7340 was known for its ability to read and write data on magnetic tape, providing an efficient means of data storage and retrieval at the time.

The Ryu–Takayanagi conjecture is a theoretical proposal in the field of theoretical physics, particularly in the context of quantum gravity and the AdS/CFT correspondence, which relates gravitational theories in Anti-de Sitter (AdS) space to conformal field theories (CFT) defined on the boundary of that space.

A **current loop** is a method used in industrial automation and instrumentations for transmitting analog signals over long distances. The most common type is the 4-20 mA current loop, where a current of 4 milliamperes represents the lowest end of the measurable range (often 0), and 20 milliamperes represents the highest end (often 100%).

A nautical mile is a unit of measurement used primarily in maritime and aviation contexts to measure distances over the Earth's surface. One nautical mile is defined as exactly 1,852 meters (or approximately 1.15078 statute miles). The nautical mile is based on the circumference of the Earth and is equivalent to one minute of latitude.

Uranium emits them, you can see their mass to charge ratio under magnetic field and so deduce that they are electrons.

Caused by weak interaction TODO why/how.

The emitted electron kinetic energy is random from zero to a maximum value. The rest goes into a neutrino. This is how the neutrino was first discovered/observed indirectly. This is well illustrated in a decay scheme such as Figure "caesium-137 decay scheme".

The half-life of radioactive decay, which as discovered a few years before quantum mechanics was discovered and matured, was a major mystery. Why do some nuclei fission in apparently random fashion, while others don't? How is the state of different nuclei different from one another? This is mentioned in Inward Bound by Abraham Pais (1988) Chapter 6.e Why a half-life?

The term also sees use in other areas, notably biology, where e.g. RNAs spontaneously decay as part of the cell's control system, see e.g. mentions in E. Coli Whole Cell Model by Covert Lab.
