A record carrier includes a first stream of data representing a video item, a second stream of data representing a graphics item, and a control program for controlling interactive playback of the items. The program has a first and a second program portion. The first program portion includes primary data, relating to shape properties of a graphics object. The second program portion is to be executed after the first program portion when user input complies with a predetermined condition specified in the program. The second program portion specifies a visual feedback in response to the user input and includes secondary data, relating to at least an additional visual property of the graphics object.

The method set forth in claim 6, wherein said step (d) records said information on the start position in a management information area pertaining to each sector. 8. The method set forth in claim 6, wherein said information on the start position is information on the size of a latter part of a transport stream unit recorded across two sectors. 9. The method set forth in claim 8, wherein said information on the start position is recorded in a management information area of the sector in which the latter part of said transport stream unit is recorded. 10. The method set forth in claim 1, wherein said step (c) comprises the steps of: (c1) checking whether said sector is the last sector of a stream object unit, depending upon the checked result of said step (b); (c2) determining whether to record a transport stream unit across the remaining area of said sector and the next sector, depending upon the checked result of said step (c1); and (c3) recording the transport stream unit according to the determination result. 11. The method set forth in claim 10, wherein said step (c2) records a transport stream unit in the next sector instead of recording the transport stream unit across two sectors if said sector is the last sector of the stream object unit. 12. The method set forth in claim 11, wherein said step (c3) pads the remaining area of said sector with null data. 13. An apparatus for recording digital data streams, comprising: recording means for recording received digital transport stream units sequentially in a sector which is a physical recording unit, each transport stream unit having a predetermined length; and control means for checking whether the size of the remaining area of the sector is less than the length of a transport stream unit and controlling said recording means to record a transport stream unit across the remaining area of the sector and the next sector, based upon the checked result. 14. The apparatus set forth in claim 13, wherein said control means creates information on the number of transport stream units contained in a sector and controls said recording means to record the information, the number varying based on a transport stream unit is recorded across two sectors. 15. The apparatus set forth in claim 13, wherein said control means creates information on a start position of a first transport stream unit of a sector and controls said recording means to record the information, the start position varying as a transport stream unit is recorded across two sectors. 16. The apparatus set forth in claim 15, wherein said information on the start position is information on the size of a latter part of a transport stream unit recorded across two sectors. 17. An apparatus for recording digital data streams, comprising: a data receiver to receive digital transport stream units, each transport stream unit having a predetermined length; a data recorder to record digital transport stream units received from said data receiver sequentially in a sector of a recording medium which is a physical recording unit; and a controller to check whether the size of the remaining area of the sector is less than the length of a transport stream unit and to control said data recorder to record a transport stream unit received from said data receiver across the remaining area of the sector and the next sector, based upon the checked result. 18. The apparatus set forth in claim 17, wherein said controller creates information on the number of transport stream units contained in a sector and controls said data recorder to record the information, the number varying based on a transport stream unit recorded across two sectors by said data recorder. 19. The apparatus set forth in claim 17, wherein said controller creates information on a start position of a first transport stream unit of a sector and controls said data recorder to record the information, the start position varying as a transport stream unit is
