Abstract

PURPOSE: To prevent the content of a normal business medium from being erased due to the erroneous operation upon a recording function inspection of a magnetic recording and reproducing apparatus by making different the information recording systems of a recording function inspecting medium and the normal business medium.
CONSTITUTION: There are recorded on a magnetic card by a head 5 such pieces of information as are cerected with timing marks, data starting marks,data ending marks and erroneous data detecting marks BBC. During reproduction, the information detected by a head 10 is converted into parallel data 14 and 15 so that the starting and ending marks are detected at 7 while designating the detected marks in response to the signals 12 from a control circuit 1. moreover, the card to be used in the inspection of the recording function is reproduced, and the detected marks of normal business are designated by the signals 12. In case no starting mark is detected, the information of the preset type is recorded and reproduced. The starting and ending marks in this instance are made different from those of the business medium.
