Abstract: PURPOSE: A method for recording and reproducing a data of a recorder is provided to grant read/write authority by setting up a password. CONSTITUTION: If a user inserts an optical disk(26) into an optical disk driving apparatus(200), the optical disk driving apparatus ascertains whether the inserted recordable optical disk(CD-R or CD-RW) is a blank disk or a disk having a password approachable to the recordable optical disk at a step 11. The ascertained result is reported to an authoring software, which is mounted on a hard disk(10) and is executed by a central processing unit(11). The user inputs an original password at a step 20. The central processing unit(11) constitutes a packet command according to an ATAPI protocol by using the inputted password and a password recognizing opcode, and transfers the packet command to the optical disk driving apparatus(200) through an ATAPI interface part(21) of the partners's side at a step 21. A micom(32) copies the password several times and forms the same into blocks having a uniform size and transfers the blocks to a digital record signal processing part(23). The digital record signal processing part(23) adds an error correction parity for reliability of record and reproduction to the password blocks and generates an error correction code blocks(ECC blocks). A channel bit encoder(24) converts a digital bit stream output by the digital record signal processing part(23) into a pulse-width modulated signal to be recorded on the optical disk(26) and applies the same to a light driver(25). The micom(32) controls a pick-up part(27) to be positioned on a pertinent record area of a file system through a servo part(30), controls the optical driver(25) to output a record signal due to an optimum light driver current. The light driver(25) applies the signal according to an optical disk driving force to the pick-up part(27) and permits the signal of the pulse-width modulated password blocks to be recorded on the record area of the optical disk file system at a step 22. The micom(32) memorizes the record passwords. An encoder encodes the inputted data by using an equation of higher degree generated by the password, and the encoded data is recorded on the data area on the optical disk(26) by the pick-up part(27).
