When you purchase a CD or a record, do you know which will sound better and last longer?

Do you know the components of Digital and Analog recording?

In this essay I will define, explain and compare the similarities of Digital and Analog recording.

Analog recording means, "the wave form of the recorded signal resembles the wave form of the original." (Alten)

Records were of the few amongst the beginning of Analog recording, however compared to Digital recording, Analog has "a low frequency control due to the fact that the amplitude of the electrical signal produced was proportional to the side to side velocity of the stylus." (Walsh)

Something in which people listen to frequently is Audiotape. Audiotape in Analog recording is defined as "the conversion of electrical signals into magnetic signals in the recording stage and then it is encoded onto tape. When the tape is played back, magnetic signals a

The functions of the three different types of Heads are as follows. The Erasehead; "neutralizes the polarities of the magnetic particles to remove sound from the tape." (Alten) This is why most people are careful of hitting that record button by accident, while playing valuable information. The Recordhead is the one we use when dubbing a song or our voices to tape. "It carries two signals, the record bias current and the audio current. This signal is fed to the recorder from the original sound." (Alten) The Playhead "transduces the magnetic field from the tape back into electricity energy." (Alten)

When being compared to Analog, Digital wins because it as more options. For instance, when an Analog reel to reel recorder is compared with a 16 bit Digital recorder "total harmonic distortion on an Analog recorder is 0.2% and on Digital it's 0.005%. Wow and Flutter is 0.03% on Analog and unmeasurable on Digital. Loss of S/N during copying for analog is 3db and on Digital none. The one that is looked at th
