Abstract
A time display device for an apparatus for playing information recorded on an optical disk includes a first input device for specifying a total playing time and a second input device for specifying portions of the disk to be played. A time adding unit obtains a sum of the playing times of the portions of the disk specified by the second input device. A subtracting unit obtains a subtracted value by subtracting the sum obtained by the time adding unit from the total playing time. The total playing time is then displayed in a numerical fashion, whereas the sum obtained by the adding unit is displayed in a bar graph fashion.
