8、ion of BS 5550 has been prepared under the direction of the Cinematography and Photography Standards Policy Committee. It is identical with ISO 9525:1988 “Cinematography Recording head gaps for two sound records on 17,5 mm magnetic film Positions and width dimensions”, published by the International
9、 Organization for Standardization (ISO). A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

16、n Table 1. 3.2 The magnetic head gaps shall be physically in line at an angle of 90 3 to the direction of the film travel. 4 Recorded characteristic The recorded characteristic shall be in accordance with ISO 1189. 5 Velocity 5.1 The sound records are intended for use at velocities of 24 frames (app
17、roximately 45,6 cm or 18 in) per second, or at 25 frames (approximately 47,5 cm or 18,7 in) per second. 5.2 The tolerances given in ISO 1189 permit a choice of operating conditions such that the recorded characteristic conforms to ISO 1189 even though the recording is intended for either 24 or 25 fr
18、ames per second, and the reproduction is conducted at the other velocity. 6 Track usage 6.1 The two tracks specified in this International Standard may be used for either related or unrelated material. 6.2 When used for two-channel stereophonic programme material, track 1 shall be used for the left
19、(as viewed from the auditorium) loudspeaker channel. Track 2 shall be used for the right (as viewed from the auditorium) loudspeaker channel. 6.3 The control track shall be used for recording other information and for address systems in analogue or digital form.
