When the user enters a command to eject an optical disc from an optical-disc apparatus by operating an input unit, a CPU records information such as an operating mode and a location accessed immediately prior to ejection of the disc into a RAM unit as resume-function related information. The resume-function related information is then supplied to the optical disc to be recorded thereon by way of a write-in channel buffer, a switch, an ECC circuit, an RF & demodulation/modulation circuit and an optical head. Accordingly it is possible to make an access to a location on an optical disc accessed immediately prior to ejection of the disc from an optical-disc apparatus when the disc is reinserted into the optical-disc apparatus.

A recording apparatus performs bit rate conversion on an input stream and records the input stream with additional data such as captions and a weather forecast left therein into a recording medium in consideration of the remaining capacity thereof. A recording apparatus (10) performs bit rate conversion on an input stream including video data, voice data and additional data and records the converted input stream. The recording apparatus (10) comprises a control portion (15) which calculates a target total bit rate which is a target of the input stream on the basis of the recording time of the input stream and the remaining capacity of the recording medium and sets a target bit rate of the video data with respect to the calculated target total bit rate and a transcoder (13) which measures an actual total bit rate of the input stream after starting the bit rate conversion on the basis of the target bit rate of the video data. The control portion (15) adjusts the target bit rate of the video data on the basis of the difference between the actual total bit rate and the target total bit rate so that the input stream including the additional data may fall within the remaining capacity of the recording medium.

In the invention herein a recordable optical disc is provided with embossed windings of a spiral track or circular tracks in a recording layer of phase change material and with embossed address/timing information located between adjacent windings. User data is received for recording on the disc. The data is written by controlling a laser beam scanning the winding to form marks of different phases of the phase change material at a higher disc speed while reading an address from the disc. The writing is occasionally interrupted in order to calibrate write parameters in order to improve the write quality. After the calibration linking is performed by jumping to a position just before the writing was interrupted, and determining the current position depending on an address read from the disc, and tracking to the position that the writing was interrupted. When an error occurs in reading the address information from the disc during linking at a higher disc speed, then the disc speed is reduced to a lower disc speed and linking is performed at the slower disc speed. After successful linking, writing of the user data continues at the lower disc speed or the disc speed is increased and writing continues at the higher disc speed.

A reproduction apparatus is provided which is capable of reproducing audio data continuously and unbrokenly, without increasing the storage capacity of a storing means. An optical pick-up 101 reads audio information from an optical-disk medium 120 and reads, from the optical-disk medium 120, image information recorded in a position different from the audio information; a first audio compression section 104 lowers the capacity of the read audio information; a first audio storage section 105 stores the audio information whose capacity has been lowered; an audio output section 111 reproduces the stored audio information; a first image storage section 114 stores the read image information; an image output section 118 reproduces the stored image information; the audio information includes first audio information and second audio information which is continuously reproduced after the first audio information; and the first audio compression section 104 lowers the capacity of the first audio information, so that the reading of the second audio information is completed before the reproduction of the first audio information is completed, for the period of time when the image information is reproduced.

An optical disc includes a data area and a time map area, the data area recording a video object that includes a plurality of data units, each of which contains at least one picture, and the time map area recording a table showing recording addresses of data units, the addresses corresponding to a plurality of reproduction times that belong to a period during which the video object is reproduced, each of the data units containing a picture to be reproduced at a corresponding one of the plurality of reproduction times, wherein the table records difference times, each of which corresponds to one of the plurality of reproduction times shown in the table and is a difference between the one of the plurality of reproduction times and a reproduction time of the first picture of a data unit that includes a picture to be reproduced at the one of the plurality of reproduction times. Recording apparatus and a computer-readable storage medium storing a program for recording such a disc are disclosed.
