The object
19、of this standard is to enable users of magnetic recording systems to compare technical product data from different manufacturers and to enable compatibility within the VTR format. Currently available VTRs, adjusted with the IEC reference tape appropriate to the corresponding IEC VTR standard, should
20、 give satisfactory results with currently available tapes. The information within this standard covers existing IEC formats. For future formats the corresponding information will be included in the IEC standard which defines the individual system. 2 Normative references The following standards conta

25、tape an unrecorded magnetic tape with specified audio and video characteristics, selected as a reference, to enable a comparison to be made with other magnetic tapes or to measure characteristics of magnetic tape recorders IEV806-05-59 modified 4 Source and maintenance of reference tapes Reference t
26、apes shall be provided by agreed organizations which have carefully selected a batch of tapes of the VTR formats listed inTable 1. Reference tapes shall be periodically reviewed to ensure that they are compatible with currently available video tapes and video tape recorders. The reference tapes shal
27、l be certified by the issuing IEC National Committee and agreed to by the IEC. The reference tape for a particular VTR system shall be valid for all television standards covered by the corresponding VTR standard.EN61105:1993 4 BSI 01-2000 The IEC reference tapes are listed inTable 1 below. Table 1 V
28、TR systems and reference tapes 5 Electromagnetic parameters The IEC reference tape is used as the0dB reference for the following electromagnetic compatibility parameters. The data for the IEC reference tapes is given inAnnex A. 5.1 Video: Optimum recording current. 5.2 Audio: a) optimum bias; b) low
29、-frequency sensitivity; c) high-frequency sensitivity. 5.3 The above parameters are the basis for comparison of video, tapes and video tape recorders measured in accordance with IEC698 and IEC735. 5.4 Tolerances of reference tapes should be specified by the manufacturer and controlled accordingly. 6
30、 Alignment In order to assure matching of mass produced video tape recorders and video tapes, alignment of video tape recorders shall be such that compatibility with the relevant IEC reference tape is obtained. 7 Determination of the tape It is the task of the National Committee which presents each
31、IEC VTR standard to determine and incorporate the appropriate information concerning the calibration and reference tape applicable to theVTR standard.
