Storage medium, recording apparatus, playback apparatus, recording method, and computer-readable storage medium

An apparatus for recording still picture data (VOB) and still picture group management information (VOBGI) for managing N still picture data (VOB) as a still picture group (VOBG) onto a storage medium, where N is an integer number equal to or larger than one, wherein said still picture group management information (VOBGI) includes a first recording time (F_RECTM) at which the still picture data (VOB) in said still picture group (VOBG) was recorded first and a last recording time (L_RECTM) at which the still picture data (VOB) in said still picture group (VOBG) was recorded last, said apparatus comprising:

• means for comparing a recording time (RECTM) of said still picture data (VOB) with said first recording times (F_RECTM) stored in said still picture group management information (VOBGI) corresponding to the still picture group (VOBG) belonging to said still picture data (VOB);
• and
• means, if said recording time (RECTM) is later (RECTM>L_RECTM) than said last recording time (L_RECTM), for replacing the content of said last recording time (L_RECTM) by said recording time (RECTM) and recording thereof.

A computer-readable storage medium storing thereon a procedure for controlling a computer to record still picture data (VOB) and still picture group management information (VOBGI) for managing N still picture data (VOB) as a still picture group (VOBG) onto a storage medium, where N is an integer number equal to or larger than one, wherein said still picture group management information (VOBGI) includes a first recording time (F_RECTM) at which the still picture data (VOB) in said still picture group (VOBG) was recorded first and a last recording time (L_RECTM) at which the still picture data (VOB) in said still picture group (VOBG) was recorded last, said procedure comprising the steps of:

• comparing a recording time (RECTM) of said still picture data (VOB) with said first recording time (F_RECTM) stored in said still picture group management information (VOBGI) corresponding to the still picture group (VOBG) belonging to said still picture data (VOB);
• and
• if said recording time (RECTM) is earlier (RECTM<F_RECTM) than said first recording time (F_RECTM), replacing the content of said first recording time (F_RECTM) by said recording time (RECTM) and recording thereof.
