This heading covers :
(1) Recorded discs tapes wires strips etc. whatever the stage of manufacture at which they are presented (e.g. the discs or wax blanks mentioned in Explanatory Note to heading 85.23 impressed with sound); these are thus starting points in the production of commercial records.
(2) Recorded media constituting intermediate products in the manufacture of commercial records from the recorded discs or wax blanks referred to above. The main stages in this manufacture are : The disc recording is treated with a wetting agent and a sensitising solution (e.g. stannous chloride) and then rendered conductive by a thin coating of gold or silver applied either by electrolysis or with a spray gun. After this treatment the disc is placed in an electrolytic bath in which it receives a deposit of metal (usually of nickel or copper). This is detached as a shell carrying negative grooves known as the " master " record. A second electrolytic process is used to produce a further shell of metal the positive- grooved " mother " record from which a negative " stamper " is obtained. This is soldered on to a steel or copper plate chromium plated perforated at the centre surface-worked in various ways and then constitutes the final " shell " from which records are mass-produced on a press.
(3) Commercial gramophone records. These are manufactured from vinyl resins or other plastics mixed with lamp black and stabilising agents.
(4) Mechanically recorded tapes or films which after appropriate treatment (usually by cathodic pulverisation of silver in a vacuum) have been plated with metal and serve as matrices (as in the case of the discs mentioned above).
(5) Commercial reproductions of the tapes or films mentioned in the preceding paragraph obtained by superimposition and contact under pressure with the riginal tape or film heated to about 400 øC
. (6) Magnetic discs strips tapes films and wires on which a recording has been made as described in the paragraph of Explanatory Note to heading 85.20 dealing with magnetic sound recording apparatus. Magnetically recorded media for the scoring of films as well as very narrow
sound tracks for gluing to one edge of films or perforated magnetic strips the unwinding of which is synchronised with that of the film.
(7) Magnetic tapes (video tapes) holographic image tapes and discs (video
discs) on which are recorded television image and sound.
(8) Media on which phenomena other than sound or image have been recorded
(e.g. magnetic tapes disc packs diskettes and cassettes for machines of headings 84.69 to 84.72).
(9) Discs for sound reproducers with a laser optical reading system (compact discs).
Media recorded with sound or similar recording whether or not presented together with the apparatus for which they are intended or assembled with constituent parts of machines of headings 84.69 to 84.72 (e.g. disc packs) are in all cases to be classified in this heading.
This heading excludes :
(a)Photographic or cinematographic films with one or several sound tracks which have been recorded by a photoelectric process (CHAPTER37).
(b)Data-bearing paper tapes or punch cards the recording of which has been made usually by perforatio(CHAPTER48).
