It doesnt matter whether magnetic particles are separate, you're not storing a value per particle, you're reading the amplitude of the magnetic field at a particular region of the tape. The amplitude of the magnetic field under the record and/or playback head is continuously variable.sonicpowa wrote:How come a tape is any more "continuous" signal than digital, the storage medium is just different: digital (separate) samples vs. magnetic (separate) particles?woggle wrote:Tape records a continuous signal --
Recording onto magnetic tape is basically transduction. The pressure change in air moves a diaphragm which converts the amplitude of the pressure into an electrical signal, and the electrical signal gets converted into a magnetic field, which is then recorded onto tape. Recording digitally involves recording time-separated measurements of a signal, not a signal.
