This underlayer can be thought of as part of the write head, completing a magnetic circuit which transects the data storage layer. Having more of the magnetic flux penetrate the data storage layer makes the write head more efficient than a longitudinal head, produces a stronger write field gradient, and thereby allows the use of the higher ...
Magnetic storage media, primarily hard disks, are widely used to store computer data as well as audio and video signals. In the field of computing, the term magnetic storage is preferred and in the field of audio and video production, the term magnetic recording is more commonly used. The distinction is less technical and more a matter of ...
Heat-assisted magnetic recording (HAMR) (pronounced "hammer") is a magnetic storage technology for greatly increasing the amount of data that can be stored on a magnetic device such as a hard disk drive by temporarily heating the disk material during writing, which makes it much more receptive to magnetic effects and allows writing to much smaller regions (and much higher levels of data on a ...
The evolution of the disk's axial precession is easily visualized in a slow motion video by looking at the side of the disk following a single point marked on the disk. The evolution of the rotation of the disk is easily visualized in slow motion by looking at the top of the disk following an arrow drawn on the disk representing its radius.
No matter how many problems we solve, there will always be other problems that cannot be solved within the existing rules. […] Because of Gödel's theorem, physics is inexhaustible too. The laws of physics are a finite set of rules, and include the rules for doing mathematics, so that Gödel's theorem applies to them." [48]
Modern compact discs support a writing speed of 52× and higher, with some modern DVDs supporting speeds of up to 24×. [4] Writing a DVD at 1× (1 385 000 bytes per second) [5] is approximately 9 times faster than writing a CD at 1× (153 600 bytes per second). [6] However, the actual speeds depend on the type of data being written to the disc ...
How are you holding up? Are you over it? I'm over it. I'm fine. At least, at times I think that. It's obviously not what I wanted but that's life. I'm not going to lie. It been an adjustment, but ...
MinutePhysics is an educational YouTube channel created by Henry Reich in 2011. The channel's videos use whiteboard animation to explain physics-related topics.Early videos on the channel were approximately one minute long. [2]
