  1. 1. CD UVI Tape Mini disc Hard disc A CD (compact disc) is a digital disc used to store data. It was developed to store and develop play back sound recording. Just like the CD a DVD is an optical storage format. DVD’s offer higher storage capacity than compact discs while having the same dimensions A cassette (MC) is a magnetic tape recording format for audio recording and playback. Compact cassette’s come in two forms, either already containing content as pre-recorded cassette, or as fully recordable ‘blank’ cassette. The mini disc is an obsolete magneto optical disc based data storage device for seventy four minutes and later eighty minutes, of digitized audio or 1 gb of HI – MD data. A hard disk drive (HDD) is a data storage device used for storing and retrieving digital information using rapidly rotating discs coated with magnetic material. Data is read I a random access manner, meaning individual blocks of data can be stored or retrieved in any order rather than sequentially.
  2. 2. Cable Signal flow Direct injection Multi track A cable is most often two or more wires running side by side and bonded, twisted or braided together to form a single assembly, but can also refer to a heavy strong rope. In electrical engineering cables are used to carry electric currents. Audi signal flow is the path an audio signal takes from source to output, including all the processing involved in generating audible sound from electronic impulses or recorded media. A DI unit also known as a direct injection or input is a device typically used in recording studios to connect a high – impedance, line level, unbalanced output signal to a low- impedance microphone level balanced input, usually XLR connector. Multitrack recording is a method of sound recording that allows for the spate recording of multiple sound sources to create a cohesive whole.
