摘要 The present invention is a device for and method of viewing a magnetic pattern recorded on magnetic media. The device includes a base. The base has an opening and includes registration marks for aligning the magnetic media as desired. The base is attachable to a viewer. A guide is connected to the base so that it slides within the opening in the base. The guide also has an opening. An inflatable bladder is attached to, and under, the guide. The inflatable bladder fills the opening in the guide. A holder is attached to the base so that it can slide along the base and be closed onto the guide. The holder also includes an opening. A magnetic garnet film is set within the opening in the holder. A magnetic media is placed on the guide. The holder is closed onto the magnetic media and the guide. The inflatable bladder is inflated so that the magnetic media is brought into physical contact with the magnetic garnet film. The pattern on the magnetic media is transferred onto the magnetic garnet film. The viewer is used to view the magnetic pattern transferred to the magnetic garnet film.
