Magnólemezek

Magnólemezek, also known as magnetic disks or magnetic storage media, are a type of data storage technology that uses magnetic particles to encode and retrieve digital information. These disks are composed of a flat, circular plate made of a non-magnetic substrate, such as aluminum or glass, coated with a thin layer of magnetic material. The magnetic layer is divided into concentric tracks, which are further divided into smaller sectors. Data is written to and read from these sectors using a magnetic head that moves across the disk's surface.

Magnólemezek were first introduced in the 1950s and have since evolved significantly. Early magnetic disks, such as the IBM 350 RAMAC, were large and expensive, with storage capacities measured in megabytes. Over time, advancements in technology led to the development of smaller, more affordable disks with higher storage capacities. Today, magnetic disks are commonly used in various applications, including personal computers, servers, and data centers.

One of the key advantages of magnólemezek is their high storage density and relatively low cost per gigabyte. However, they also have some limitations, such as slower access times compared to solid-state drives (SSDs) and a higher risk of data loss due to physical damage or magnetic interference. Despite these drawbacks, magnetic disks remain a popular choice for many storage needs due to their reliability and affordability.
