Claims (4)

  1. Porte-disque pour un disque (CD) dans un appareil d'enregistrement et/ou de lecture magnéto-optique dans lequel le disque (CD) est maintenu sur l'un des côtés par une première roue (R1), dans lequel de l'autre côté un premier bras avec une seconde roue (R2) peut pivoter autour d'un axe (A1) contre la première roue (R1) pour centrer le disque (CD) et dans lequel un électroaimant (M) est prévu pour l'inversion magnétique du disque, électroaimant qui se trouve sur un second bras (AR2) qui est pivotant autour d'un axe (A2) contre le disque (CD), caractérisé en ce qu'un lever (H) est fixé en étant rotatif autour d'un axe (A3) sur le premier bras (AR1), que le second bras (AR2) avec l'électroaimant (M) repose sur l'un des bras (AR3) du levier (H), qu'il est prévu une butée (AS) pour l'autre bras (AR4) du levier (H), que, lorsque le premier bras (AR1) s'éloigne du disque (CD) par pivotement, l'un des bras (AR3) du levier (H) pousse le second bras (AR2) avec l'électroaimant (M) loin du disque (CD), que l'autre bras (AR4) du lever (H) bute contre la butée (AS) si bien que le levier (H) est tourné autour de son axe (A3), ce par quoi l'un des bras (AR3) du levier (H) pousse le second bras (AR2) encore plus loin du disque (CD).
  2. Porte-disque selon la revendication 1, caractérisé en ce que le second bras (AR2) est poussé au moyen d'un ressort contre l'un des bras (AR3) du levier (H).
  3. Porte-disque selon la revendication 1 ou 2, caractérisé en ce que le levier (H) est parallèle à la surface du disque en mode lecture.
  4. Porte-disque selon la revendication 1, 2 ou 3, caractérisé en ce que les deux bras (AR3, AR4) du levier (H) sont rotatifs l'un par rapport à l'autre et qu'un ressort maintient les deux bras (AR3, AR4) parallèles l'un à l'autre.
