A microphone that comes without a cable and that can be connected directly to the sound recording or amplifying equipment is a wireless microphone. A German equipment manufacturer claimed in the year 1962 that they invented the first wireless microphone.

Though various individuals and organizations claim that they were the first to invent it, history says that Rex Harrison made the first use of wireless microphone for his film My Fair Lady in the year 1964.

While buying a wireless microphone one should be aware about which kind of system suits the need the best. Apart from this, the buyer must have a good knowledge of the situation for which it is being bought. Setting up of wireless technology is a bit difficult because the whole process is not limited to only plugging in and out. So, before going for this microphone a precise and clear technical knowledge is essential.

Whatever be the type of the transmitter, the buyer must check the battery to determine whether it is fresh or not. You should remember that battery life varies from system to system and if the battery has served more than half the assured life it must be replaced.

Various kinds of frequencies and transmission technologies are also to be taken care of. Wireless microphones have the ability to transmit radio waves with the help of UHF or VHF frequencies, FM or AM. The VHF Microphones are fixed frequency type and therefore the user cannot switch over to other frequencies if hindrance occurs.

UHF microphones can be operated in a place only depending on the national regulation of the country. In some countries the government considers all radio frequencies as their military assets. Not only this, using radio transmitters and wireless microphones is considered as a punishable offense. So their use requires a license issued by the government.

The use of wireless microphones has both advantages and disadvantages. They save the users the troubles caused by a constant moving of the cables. Thus the artist or the user can enjoy the freedom of movement.

One of the disadvantages of wireless technology is that it can be operated only for a limited period of time. There is the possibility that interference of other radio equipments may affect the system though this may vary from model to model.

The other points that a buyer must keep in mind are that the microphone should be easy to hold so that the hand can be rested in a comfortable position. This is equally important when wireless microphones are bought for the purpose of live performances.

The microphones must be able to handle high Sound Pressure Levels or SPL. There might be buyers in the market who are technically not so knowledgeable. They must always ask for the user manual to know how it is operated

Sony introduces its new and improved backup storage tape cartridge DAT160 on April 1, 2008. The Sony DAT160 tape (DGDAT160) has a native capacity of 80 GB and 160 GB compressed capacity. Sony DAT160 cartridge is a dual-layer technology that has extremely thin layer. The DAT 160 tape has a higher linear density recording. The Sony backup tape offers reliability and performance. The noise level is low, even in high frequency band.Has the ability to perform repeated operations of read-write.

The new Sony tape is easy to use and easy to navigate. Sony has developed the support band DAT160, which can protect data on the effects of heat. The tape loading and unloading is stable. Sony also make a series of tests simulating the transport and storage in the selection of materials and the cartridge so that the cartridges have sufficient strength againstFluctuations in temperature.

This tape backup ensures stable tape travel, the damage has reduced the tape to read and write. These backup tapes were tested by dropping them, and even the original data is completely recovered. Tape backup Sony has more impact resistance with the addition of polycarbonate for the cartridges. DAT160 resistance is 15 times more than polystyrene, which is commonly used in the videotapes.

The band is moreRigid and robust, because the ultrasonic welding for the assembly of the tape used. Therefore, the data is secure, even if the tape is damaged by the impact drop. The Sony backup tape is robust against abrasion by a metal guide pin that is used at the end of magnetic tape. DAT160 tape can be run more than 20,000 cycles repeated column stable with metal guides. The recording method that is used for inclusion in the DAT drives is called a helix "method of scanning. Thewhole process of inclusion in the DAT drives and the video cassette recorder (VCR) is the same. The DAT tape drive uses 2 test for the purpose of the letter and the other 2 heads to read data. Examination of the data collected is done through the head. In the case where errors in data collection, data rewritten by the write heads.

The DAT drive is a special software called "recovery software", which will save the file directory. DDS (DigitalData Storage) was more than DAT Digital Audio Tape DAT technology called. "The" Digital Audio Tape DAT technology "is considered one of the most productive of all the other formats of tape backup.

According to the results of a survey, nearly six million readers have sent since 2000. The latest addition to the family is the DAT DAT 160 tape drive. The technology of DAT-160 is the previous DAT technology and is very similar to the technique ofPrevious generations of digital audio recording. The main advantage of DAT technology, which made it so popular is that they are at a low cost of ownership offers and guarantees the best results. The contact angle and the speed of the drum, both contribute to the speed of data transmission in digital audio tape (DAT), responsible for technology.

DAT drives of previous generations had the angle of curvature of 90 degrees, while the new DAT-160-drive contact angle of 180 degrees. Therefore, this extended range of 180Statements contained in the new DAT160 tape drive will help the band and head to improve the contacts. Thus, in this way increases the speed of data transfer from DAT-160 drive, and thus improves the efficiency of the tape drive.
