发明名称 Recording apparatus for a drivable record carrier
摘要 A recording apparatus for a drivable record carrier which can be moved past a scanning element of the apparatus comprises a marking device for making marks of different types on a marking carrier to identify specific passages on the record carrier. A marking element of the marking device is guided along a line and, to form the marks, it can be moved, starting from the line, by means of an actuating device in a first direction perpendicularly to said line and in a second direction opposite to said first direction. In order to obtain marks of a first type and a second type the marking element can form strokes on the marking carrier, which extend transversely of the line in the first direction or in the second direction only. Moreover, in order to obtain marks of at least one further type by means of the marking element, strokes can be formed on the marking carrier, which strokes extend transversely of the line both in the first direction and in the second direction.
