The disks are covered with a magnetic film of terbium ferrite cobalt.

Zip, I recorded them on magnetic film.

These have to be mixed and dubbed onto one magnetic film.

One "frame" on the magnetic film equals one frame of picture.

For stereophonic dialogue, conventional 35 mm magnetic film was used.

The recording of the score was done on 35mm magnetic film.

At the same time music tracks recorded on nitrate film or magnetic film had begun to deteriorate.

The tracks are very large and the magnetic film moving at the normal speed of 24 frames per second, gave very good sound reproduction.

Some are equipped with dual sets of sprockets that can use more than one size of magnetic film, 16mm or 35mm.

His special interests are in spin dynamics, material properties of thin magnetic films and multilayers.
