distance, the higher the flexibility of the head reading data), the head will slowly be moved outward from the start Stop area, the head reads the data of the outermost 0 tracks (guided by The head is radially moving along the diameter, the disc rotates, and a circle of data is read. • Return to the start-stop area when not working. Spec version: 1. The disk reads and writes are carried out according to the cylinder, starting from 0, re

motor and are rotated at high speed by the spindle motor. The capacity of each platter is called a single disc capacity, and the capacity of the hard disk is the sum of all the platters capacity. Early HDD due to the low single disk capacity, so, more platters, and some even up to 10 pieces, modern hard disk is generally only a few pieces of the disc. All platters in a hard drive are exactly the same, otherwise the control section is too complex. A brand of a series are generally used the same

of multiple audio tracks. Simply append data to the back of the previous audio track by adding one more audio track,But do not forget to change the NN (number of tracks) in the file header). First watch the global audio track. Global audio tracks include additional information about a song (such as title and copyright), Song speed, and system code (sysx. Both gl

It is equivalent to a wave file and does not require decoding. You can directly input a Power Amplifier for DA conversion. Because of the large bit rate and volume, in the DVD era, audio tracks are usually used in two-channel music discs. When the Blu-r

FW: http://www.ai-junkie.com/misc/hannan/hannan.html Some time ago I corresponded with Jeff Hannan of codemasters about his work on the game Colin McRae's rally2. I knew that Jeff had trained neural networks to control the cars and I was curious to learn more about It. jeff kindly agreed to answer my questions and has recently given me permission to make them available online. I know for sure versions of you will find his notes very interesting. so here They are... Cheers Jeff! (Prior to re

workstation-class PCs and servers, and therefore use more advanced techniques, such as high speeds of 15000rpm discs, and lower CPU usage when data is transmitted, but the unit price is also more expensive than ATA and SATA drives of the same capacity.4. Reference parameters of the disk:(1) capacity(2) Buffer memory: The hard disk contains a buffer memory, this memory mainly can be used in the disk cache, to speed up the system read performance(3) Speed: The hard disk is mainly using the spindl

is better designed than other version control systems because git tracks and manages changes, not files.You will ask, what is the modification? For example, you add a row, this is a change, delete a row, is also a modification, change some characters, is also a modification, delete some and add some, is also a modification, even create a new file, also counted as a modification.Why is git managing changes, not files? We still do the experiment. The f
