Vintage applied scientific discipline brings me dorsum happy memories so I ever bask learning nigh past times applied scientific discipline whenever I acquire a chance. The development of recording formats is specially mind-blowing…just to think i time upon a fourth dimension recordings were done on a slice of wire! The next recording formats were real brusk lived because the applied scientific discipline wasn’t in that location to build them equally proficient equally they could pick out been. Influenza A virus subtype H5N1 swell shame equally these recording formats in addition to their part instrumentalist machines looked genuinely great!
1. Magnetic Wire Recorder
Instead of recording onto magnetic tape, the wire recorder records onto a strand of stainless steel wire, nigh the thickness of a human hair. The wire recorder had a brief heyday inwards the belatedly 1940’s in addition to people were genuinely excited nigh what y’all could hit amongst a wire recorder. One of the most pop uses for wire recorders was equally dictation machines in addition to Webster-Chicago was the publish i build making them at the time.
2. DBX Encoded Disc
DBX dics were essentially vinyl records encoded amongst the DBX dissonance reduction system, which exclusively worked amongst a DBX decoder. The cool affair nigh the DBX disc is that y’all could withdraw heed to the master copy 100 decibel chief tape recording sound, dissimilar phonograph vinyl discs which could exclusively acquire equally high equally threescore decibels.
The chief tape good would hold out compressed downwards to 50 decibels to agree onto a DBX disc, thus the DBX decoder would in addition to thus expand the good dorsum to the master copy 100 decibels, thus you’d effectively hold out listening to the master copy good of the chief tape recording.
Digital Micro Tape
If y’all are someone who grew upward inwards early on 2000’s you’d in all probability detect difficult to imagine people using mechanical magnetic tapes; specially given the popularity of electronic storage applied scientific discipline today. The Sony NT Cassette was a digital micro tape format of the early on 1990’s that looked real much similar the Picocassette, which was the smallest analogue cassette tape ever made.
The Sony NT Cassette tape could agree 120 minutes of digital good in addition to worked on the Digital Audio Tape format, which agency the Sony NT Cassette had a rotating recording in addition to play head. The machine that played the NT Cassette was the Sony NT-2 Digital Micro Recorder, which could play digital High definition stereo good at 32 kHz sample frequency.
If y’all don’t cry back ever seeing a cassette changer that would hold out because cassette changers weren’t largely sold to the populace but used generally inwards shops or gyms. Cassette changers came inwards all shapes in addition to could concord different numbers of cassettes. There were some cassette changers that could concord a massive twenty cassettes such equally the Panasonic RS-296US (pictured below) in addition to Philips N2401 Cassette Changer, both from the early on 1970’s (the Philips N2401 genuinely held half dozen cassette tapes inwards a stack formation).
Towards the 1990’s, automatic cassette changers started appearing such equally the Sony 5-Tape Cassette Changer in addition to Pioneer CT-M55R, which pick out a carousel that spins approximately the cassette tapes, automatically selecting a tape in addition to putting it inwards the correct position.
The D-Theater tape format is some other chip of applied scientific discipline that came out inwards the belatedly 1990’s when the starting fourth dimension hard disk televisions were launched, inwards the twelvemonth 1998. D-Theater was essentially hard disk Video on VHS format in addition to the character of this tape format could fifty-fifty compete amongst the likes of BluRay in addition to hard disk DVD.
Prior to 2002, VHS in addition to DVD were the manlike individual monarch video formats but since VHS in addition to DVD could non concord total hard disk movies some other format had to hold out produced which could store at to the lowest degree 50 GB of information in addition to play it dorsum at a charge per unit of measurement of 28.2 Mbps. That’s essentially how D-Theater came nigh to fulfill the hard disk TV marketplace inwards early on 2000. The D-Theater format was essentially prerecorded D-VHS cassettes sold nether the D-Theater brand.
Another obscured in addition to largely forgotten slice of High Fidelity applied scientific discipline history is the Stereo MicroCassette metallic tape, which was depicted equally a futuristic recording format inwards the pop 1970’s motion-picture demo “A Clockwork Orange” in addition to ended upward becoming a reality inwards the 1980’s era fascination amongst everything made small.
The Stereo MicroCassette was essentially a miniaturized measure cassette amongst a dictation tape format that never genuinely took off because of the pitiful character good produced past times the slower tape speed of the microcassette format. Two pop microcassette players were the Fisher CR-M500 in addition to SONY TC-MR2 (pictured).
