Abstract:
An optical recording and/or reproducing method, and an apparatus to perform the method, the method including reading data from an original optical disc, recording the data on another recording medium, and reading the data on the other recording medium to record the data onto one or more target optical discs, wherein the reading of the data from the original optical disc through the recording of the data onto the one or more target optical discs is automatically performed in response to an optical disc copy mode being chosen.
Abstract:
In method for freeze-crushing waste resources, freezing gas is first created by collecting freezing heat source of liquefied petroleum gas during a heat exchange process between the liquefied petroleum gas and cooling gas, and then the waste resources stored in a freezing tank is frozen to a temperature where the waste resources can be easily crushed by supplying the freezing gas to the freezing tank. Next, the frozen waste resources is crushed in an crushing apparatus, after which the freezing gas is separated from the crushed waste resources in a separate apparatus and the freezing gas for is collected the purpose of reuse.
Abstract:
Disclosed is an optical recording and reproducing apparatus for making one title automatically after a relay recording and a method thereof. The disclosed method includes the steps of performing a relay recording such that some of audio visual (AV) signals that are not recorded onto an optical disc are recorded onto a recording medium in case of insufficient optical disc capacity during recording of the AV signals in a stream type; and combining said some of the AV signals with the rest of the AV signals when the relay recording is terminated and storing the combined AV signals as one title onto the recording medium. That is, one title is automatically created onto the recording medium and is subsequently copied onto one or more than one optical disc. Hence, a user can watch images recorded onto the recording medium or the optical disc and own a plurality of copied optical discs.
