ABSTRACT:
A data terminal having a reader assembly for reading a data carrier having at least one data track formed thereon and having a predetermined track width. The terminal housing has a card guide slot with a read head mounted next to the slot. The bottom wall section of the card guide slot has an upper surface characterized by a downwardly tapering portion extending from an apex point substantially underneath the data pickup transducer such that a data carrier being swiped through the guide slot is more likely to maintain contact between the bottom of the card and the apex point and thus have sufficiently accurate registration between the pickup transducer and the data stripe for accurate detection of data recorded thereon.
