Abstract
Abstract Device for recording data on or reading data from a magnetic ticket wherein a movable ticket carrier having a data detector mounted thereon is positioned for guided movement relative to a magnetic head and a member carrying coded data so that as the ticket on the carrier is moved past the magnetic head, the data detector moves past corresponding portions of the coded data member. With the magnetic head used as a recording means, the data detector is connected thereto through an amplifier. With the magnetic head used as a reader, the data detector and the magnetic head are connected to a comparator to detect correspondence between the data recorded on the ticket and the data on the data member.
