Abstract
Abstract The present invention relates to a record/playback device for magnetic recording of manual drive type in which information can be exchanged while a magnetic card is manually being driven. In the device according to the present invention a write-only magnetic head and a read-only magnetic head are provided in a magnetic card path formed within the device. Writing of information into the magnetic card is done by said write-only head, while reading of information out of the magnetic card is done by said read-only head. Of these two magnetic heads, the one for write-in is located at a specific height above the fixed card guide formed at the deepest end of the magnetic card path, while the one for read-out is located at a greater height than the one for write-in. Between these two heads there is provided a movable card guide which is free to move along the magnetic card path. When the movable card guide goes into the magnetic card path, the magnetic card guide surface of the movable card guide runs parallel to the magnetic card guide surface of the fixed card guide. Thus when a magnetic card runs along the fixed card guide, information is written into this magnetic card. When it runs along the movable card guide, information is read out of it.
