Abstract:
1. An optical disc apparatus which has at least one of title search, chapter search, and track search modes, and which performs reproduction, or reproduction and recording of information recorded on an optical disc, wherein the optical disc apparatus comprises a system controller which: when the optical disc apparatus is set at any of the modes, detects from the optical disc, as a maximum figure for search, a quantity number of recorded titles in a case of the title search mode, a quantity number of recorded chapters in a case of the chapter search mode, and a quantity number of recorded tracks in a case of the track search mode, and also calculates a quantity number of digits in the maximum figure for search; if the quantity number of digits in the maximum figure for search is two and a figure inputted for search to specify an ordinal quantity number of title, chapter, or track to be searched is smaller than a figure included in a ten's digit of the maximum figure for search, registers the figure inputted for search as a figure in a ten's digit, and also registers a figure subsequently inputted for search as a figure in an one's digit; if the quantity number of digits in the maximum figure for search is two and the figure inputted for search is equal to the figure included in the ten's digit of the maximum figure for search, registers the figure inputted for search as the figure in the ten's digit, and if the figure subsequently inputted for search is equal to or smaller than a figure included in an one's digit of the maximum figure for search, registers the figure inputted for search as the figure in the one's digit; if the quantity number of digits in the maximum figure for search is two and the figure inputted for search exceeds the figure included in the ten's digit of the maximum figure for search, registers the figure inputted for search as the figure in the one's digit; if the quantity number of digits in the maximum figure for search is one and the figure inputted for search is equal to or smaller than the figure included in the one's digit of the maximum figure for search, registers the figure inputted for search as the figure in the one's digit; and causes the title search, the chapter search, or the track search to be performed based on the registered figure for search.
