Abstract
A circuit and a method of preventing errors in recording. The circuit includes a first detector to generate a detection pulse by determining whether or not a counted value, which is obtained by counting a cycle of an input wobble signal based on a system clock signal, is in the permissible range of a constant write rate. The circuit further includes a second detector to generate a recording control signal to allow or prohibit a record operation after determining whether the detection pulse meets a predetermined lock condition or a predetermined unlock condition. The circuit prevents errors in recording prevents errors in reproduction data caused by errors in recording, by prohibiting recording if the rotation speed of a disc is not at a desired constant rate in an optical recording and/or reproducing apparatus in which data can be reproduced at a constant or a variable rate and must be recorded at a constant rate. Thus, data can be stably recorded, thereby enhancing recording quality.
