A cassette for magnetic tape recordings, having a casing with bottom and cover walls, between which two winding hubs for the tape are captured. A corrugated plastic film is located between the tape winding and the bottom and cover wall respectively, the spring constant of the corrugated film ranging from about 100 to 400 grams/mm. A flat film is disposed between the tape winding and the corrugated film to ensure even distribution of forces exerted on the tape.
