A magnetic storage medium is a type of computer storage that uses magnetism to store and retrieve digital information. These types of storage media are used in a variety of devices, including computers, laptops, and external hard drives.
There are several types of magnetic storage media, including hard disk drives (HDD), floppy disks, and magnetic tape. Hard disk drives are the most common type of magnetic storage media, and they are used to store large amounts of data in a computer or laptop. They consist of a spinning disk coated with a magnetic material, and data is written and read using a read/write head that moves over the disk.
Floppy disks are a type of magnetic storage media that were commonly used in the past, but they have largely been replaced by more modern storage technologies. They are small, portable disks that are made of a flexible material and are used to store and transfer small amounts of data.
Magnetic tape is another type of magnetic storage media that is used to store large amounts of data. It consists of a long strip of plastic or paper coated with a magnetic material, and data is written and read using a read/write head that moves along the tape. Magnetic tape is often used for backup and archival purposes, as it can store large amounts of data for long periods of time without degrading.
One of the main advantages of magnetic storage media is their relatively low cost and high capacity. Hard disk drives, for example, can store hundreds of gigabytes or even terabytes of data, and they are relatively inexpensive compared to other types of storage media. Additionally, magnetic storage media is generally reliable and durable, making it a good choice for storing important data.
However, there are also some limitations to magnetic storage media. One of the main drawbacks is that it is slower than some other types of storage media, such as solid state drives (SSD). Additionally, magnetic storage media is susceptible to physical damage, and it can be affected by magnetic fields.
Overall, magnetic storage media is a popular and effective way to store and retrieve digital information. It is widely used in computers and other devices, and it offers a good balance of cost, capacity, and reliability.

And more preferably 50 atomic% or more. Although the flash coating has been described as being produced by electroless techniques, it will be appreciated that the flash coating may be produced by electroplating the nickel on the aluminum surface. The layer 14 also has hard characteristics so that it protects the aluminum substrate 12 against becoming pitted or dented when a head 22 in FIG. D 50 denotes a linear recording density in which there is recorded magnetic information indicative of a reproductive output of a half of a reproductive output of magnetic information recorded at a linear recording density of 0 kFCI. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed. Also in the magnetic storage medium of the present invention, the dividing layer of the item 3 referenced above maintains the antiferromagnetism until at least the same temperature, and thus, as Néel temperature of the material constituting the dividing layer, 400 K is a standard. Further, in the magnetic storage medium having the primary layer 3 as mentioned above, it is preferable that an intermediate layer consisting of a non-magnetic material, which is different from the material constituting the primary layer, is interposed between the primary layer and the recording layer.

In exceeding 7 atom % in the percentage composition of W, the coercive force H c of the magnetic recording layer 3 is increased as the percentage composition of W is increased, and offers the maximum value exceeding 3500 Oe in the vicinity of 15 atom % in the percentage composition of W, and thereafter is decreased as the percentage composition of W is further increased. Thus, the CoCrPtTa alloy of the hexagonal structure is subjected to a hetero-epitaxial growth on the interface of the upper portion of the primary layer 4 consisting of CrMo10 of the body-centered cubic structure. The storage media have further advantages in that neither the media nor the magnetic head operating in conjunction with the media are damaged when the head inadvertently contacts the media. In case of the magnetic storage medium m 5 having the primary layer consisting of an antiferromagnetic material CrMn 40Pt 5, T 90 is about 10 36 which is 10 7 times of that of the medium m 4. Thus, it is considered that the magnetic storage medium, in which the primary layer is replaced, is a medium wherein T 90 is longer than the magnetic storage medium m 2 and magnetic information is stored more stably on a thermal basis. Consequently, the magnetic storage medium is favorable in orientation, large in coercive force Hc and high in resolution.
Magnetic storage
Contact between the medium 10 and the head 22 becomes an increasing likelihood as the packing density of the information on the head increases since the spacing between the medium and the head decreases with increased packing densities. . The composition according to claim 1, further comprising vanadium. Here, the interstice signifies a grain boundary. The left column of Table 2 shows a sort of media. In order to obtain high resolution, however, it is preferable that the value of Br·t is less than 100 Gauss·μm near the value of Br·t of the magnetic storage medium which is generally used. Therefore, in order to impart, to the recording layer 203, the magnetic anisotropy having the direction perpendicular to the disk surface as the magnetization easy axis, the c-axis of the hcp structure in the magnetic particle in the recording layer 203 needs to be oriented in the direction perpendicular to the disk surface.

In order to obtain a larger regenerative output keeping the value of the anisotropy magnetic field H k, which satisfies the favorable overwrite property, it is preferable that the coercive force H c is increased. Here, the material of the non-magnetic split layer 212 is not limited to this, but it may be an Ru alloy, a material disclosed in a report: S. The method according to claim 1, wherein at least one of said base film and said intermediate film is made of vanadium. A solid line a 3 shows a state that the Néel temperature of the CrRe alloy varies with respect to the additional concentration of Re. When such an alloy is used for the base film or the intermediate film, a compressive stress is applied to these films, so that the strength against damage due to contact with the head increases.
