How Tape Recorders Work
In the audio realm, magnetic tape (in the form of compact cassettes) is a popular way of distributing music.
The tape itself is actually very simple. It consists of a thin plastic base material, and bonded to this base is a coating of ferric oxide powder. The oxide is normally mixed with a binder to attach it to the plastic, and it also includes some sort of dry lubricant to avoid wearing out the recorder.
Iron oxide (FeO) is the red rust we commonly see. Ferric oxide (Fe2O3) is another oxide of iron. Maghemite or gamma ferric oxide are common names for the substance.
This oxide is a ferromagnetic material, meaning that if you expose it to a magnetic field it is permanently magnetized by the field. That ability gives magnetic tape two of its most appealing features:
You can record anything you want instantly and the tape will remember what you recorded for playback at any time.
You can erase the tape and record something else on it any time you like. These two features are what make tapes and disks so popular — they are instant and they are easily changed.
😳Why❓❓❓
What is the reason for The Ancient Practice Of Sprinkling Water Around Food Meant!
This ancient practise is believed to have started by sages in olden times, who spent most of their lives living in forest areas or in raw houses, where the floors weren’t concrete on which they sat and ate food.
Moreover, the food was mostly served on banana plantains. The food was prone to be exposed to the muddy floor making it unhealthy; which is why water was sprinkled around the plates to settle the mud or dust particles down.
Dirt contains bacteria that may contribute to allergic reactions and other health problems.
Another reason may be that sprinkling water was also a great way to keep insects and pests at bay, especially at night when there is barely any light. It is said that ants or any insect cannot cross or tread upon water.
