At +6 VU, the Type II tape displays significant amounts of signal level compression across the entire frequency range, reducing to about 2 dB of signal compression between 80 Hz and 1 kHz. Some representative measured performance characteristics of a small number of commercially available tape types are presented in the table below.
The tape head has 8, 16, or 32 data read/write head elements and 2 servo read elements. The set of 8, 16, or 32 tracks are read or written in a single, one-way, end-to-end pass that is called a "wrap". The tape head shifts laterally to access the different wraps within each band and also to access the other bands.
Some analog tape manufacturers specify frequency responses up to 20 kHz, but these measurements may have been made at lower signal levels. [16] Compact Cassettes may have a response extending up to 15 kHz at full (0 dB) recording level. [17] At lower levels (−10 dB), cassettes are typically limited to 20 kHz due to self-erasure of the tape media.
The Compact Cassette, also commonly called a cassette tape, [2] audio cassette, or simply tape or cassette, is an analog magnetic tape recording format for audio recording and playback. Invented by Lou Ottens and his team at the Dutch company Philips , the Compact Cassette was released in August 1963.
Scalable Linear Recording is the name used by Tandberg Data for its line of QIC based tape drives. The earliest SLR drive, the SLR1, has a capacity of 250 MB, while the latest drive, the SLR140, has a capacity of 70 GB. The term SLR is often used to refer to QIC tapes, as for many years they were the only drives that used them before Tandberg ...
At the end of the tape, the drive reversed the direction of tape motion, moved the read and write heads slightly vertically across the tape, and continued to write (or read) more data until the beginning of the tape was reached. This process could be repeated many times, laying down several track sets on the tape media in a serpentine recording ...

A tape head is a type of transducer used in tape recorders to convert electrical signals to magnetic fluctuations and vice versa.They can also be used to read credit/debit/gift cards because the strip of magnetic tape on the back of a credit card stores data the same way that other magnetic tapes do.
