The Iron Solution to the 2000 Iron Problem

Before the onset of 2000, about three more months. But the situation was noticeably heated. It is understandable.

But why are the prophecies given in most publications on the 2000 issue not particularly credible? It painfully thickens without explaining the details. Continue reading

Z-tracks

In devices with a moving coil there are no pre-fixed positions. Instead, they use a special guidance system (positioning), which accurately brings the heads to the desired track.

The system of precise guidance of the heads on the tracks is called a servo drive, and for its operation a feedback signal is required that carries information about the real relative position of the tracks and heads.

Temperature fluctuations do not affect the accuracy of the drive. When compressing and expanding disks (rotation, temperature), all changes in their sizes are monitored by a servo drive and the positions of the heads are adjusted. Continue reading

Ways of spreading viruses

How are viruses and, in particular, the Win95.CIH virus spread? It is generally believed that the main path is the Internet. Other viruses cause a lot of controversy about the distribution paths (spread with games, via floppy disks, etc.). In fact, any viruses are highly democratic in their habitat. The main channel for spreading viruses is the channel through which the necessary information is transmitted most intensively. What is this information: games or necessary programs – the virus doesn’t care. Continue reading
