Abstract: Partial information such as the beginning data of each of chapters is read from a CD and written in a HDD 10 at a higher speed than that in a normal reproduction while the normal reproduction is carried out using a buffer memory 8.

Abstract: Servo-pattern information is magnetically recorded on a product disc by magnetic print-through from a master medium. The master servo-writing medium is brought into close proximity with the product “slave” disc, and the two are subjected to an external magnetic field which assists in transferring magnetic servo-patterns to the slave disc in a print-through process. The preferred external magnetic field alternates and rotates with respect to the master/slave combination. In an alternative product disc structure, the magnetic layer is magnetically altered in a servo-pattern configuration. Non-magnetic portions of the servo pattern are created which define both gray code and servo burst information for the product disc.

Abstract: A signal recording device includes a signal inputting unit for inputting a signal to be recorded on a recording medium, as well as a dropout detector which detects a dropout portion of a signal output from the signal inputting unit and generates a pulse signal corresponding to the detected dropout portion. A muter mutes the signal output from the signal inputting unit during the pulse signal period. The signal recording device records on a recording medium, a signal output from the signal muter during the pulse signal period and a signal output from the signal inputting unit during all other times. Therefore, in the signal recording device of the present invention, since a signal during a dropout period is muted before being recorded, upon playback of the recorded signal, a dropout compensator in a reproducing device identifies the muted signal period as the dropout period and accurately compensates for the dropout. Therefore, noise caused by the dropout can be prevented.
