I don't think so, if it works as for the HD I read that "a degaussed drive is inoperable in any system. The magnetic erasure rearranges the magnetic field to such an extent that standard read heads are unable to find a magnetic reference point for tracking.", so that "a degaussed disk cannot be used after degaussing".
HDs have a servo platter/surface with timing and sector information magnetically written on them so degaussing destroys that and the disk is useless. These carts are more like a normal mag tape (or cassette tape) test has no pre-recorded info on them that can;t be put on by the normal device used to read/write from the medium. The servo info can’t be accessed by the normal disk heads.-kby
