Intérêt Bandes et R2R en 2022 conseils

[Isokawa]

L heure du choix approche ….
Et du choix de la calibration , quelle bande choisir …. Pour l enregistrement et pour les les quelques  bandes commerciales que je veux acheter 

Je penchais pour du LPR90 , 44 % de bande en plus, mais la SM 9000 est plus durable et peux encaisser plus en saturation  … donc SM 900 ?

 quel est l incidence de la difference de magnétisation de la bande, la duree dans le temps ? 

Tape Material: RTM SM900
Recording Speed: 15IPS-38cm/sec-510 nWb/m

Tape Material: RTM LPR90
Recording Speed: 15IPS-38cm/sec-320 nWb/m

• SM900 is a durable studio grade mastering tapes able to handle up to +6 to +9 Db saturation with minimal increase in distortion.
  
  
• LPR90, LPR35 and MDS 36 are thinner commercial grade tape with similar (but not exactly the same) magnetic characteristics as their standard play cousins. Their main advantage is economy in that you get 44% more tape and time on a reel. However you dont get something for nothing and lifespan is reduced. 
  
  
• SM900 (std play) and LPR90 (long play) have similar but not exactly the same magnetic properties despite what the manufacturer implies . So setting up on one and using the other could mean a variation  of 0.75 - 1.5 Db difference in level between std and long play and the optimum bias will also not be the same.
