In magnetic tape cartridges it is necessary to provide means for preventing re-recording over a recording which is to be retained. To enable this to be done, it is common to provide a mechanical detent which cooperates with a microswitch or the like to prevent a recording head from functioning when the detent is in a predeter- position. The present invention provides such a mechanical detent that is simple in action, positively retained in position and is unlikely to jam in the cartridge.
