Recording Technology Evolution
Technology we enjoy today are many contributed from discoveries of the pioneer in ancient. The Phonograph which was found by Thomas Edison during 1877, is the first step where the voice could recorded in a tool. With cylinder tube (wax cylinder), wrapped by soft material like candle to record voices into a media. To do play back, it need tool like a needle on Phonograph that scratched to this cylinder, produce the vibration and voice to phonograph’s funnel.
During 1887, Emile Berliner, developed Phonograph become Gramophone. The form did not much change, except the record’s systems changed from vertical to horizontal, that make the depth of the cylinder channel become more constant.
The big jump happened during 1924. With Victor Orthophonic Phonoautograph, the increase in the quality from the process of the recorder that has used the electricity power as well as the change to a funnel that produced the flat frequency response.
Magnetic record was introduced by Valdemar Poulsen with used Telegraphone during 1898. By using the magnetic strength, the moving media constantly with constant speed through recorder’s ‘head’. The electric signal, that in an analogous manner became the voice that wanted to be recorded, through this ‘head’ and produced the magnet pattern like signal that produced the voice, better than earlier technology.
Tape recorder began to be developed in Germany in year 1932. The point initially at the time of Christmas Day 1932, where the British Broadcasting Corporation the first time used tape recorder for the broadcast. Equipment that was used was Marconi-Stille recorder. The giant tape machine which used the steel knife in 3 mm and thick 0.08 mm. To produce the higher audio frequency, spent 90 metre tape per minute.
The other big jump happened in around year 1950, where recording is already multitrack. When early before only could record 1 track. During 1943, 2-track recording technology has been adopted for classic music that was produced in the year 1950. In year 1960, 2-track recording growth to 4-track recording, and the following years development continued. This multitrack recording enable several signals from several microphones to be recorded simultaneously, that will produced the voice with more stereo.
Finally around 1980, digital recording has begun to be introduced and analog tape recording socialized. With the development of the tools that periodically continued, and produce the analog recorder equipment that still could be found this time. Moreover, digital tape still was used by professional for certain situation. The tape that was increasingly small with the stereo voice that has been good, enabled musical artists could have done the recording with the implement support that has been increasingly brief.
On the end of 1990, digital recording has begun to become the standard of the recorder industry. And currently, in this millenium era, all of them increasingly became easy, brief, sophisticated, and practical. The nature of tape recording which is in earlier the design is big, now already become small as harddisk, and a funnel phonoautograph was conjured up to speaker with sophisticated kinetic technology. How its development 10 or even 100 years in the future? Let the digital and technology sophistication will answer it.
