ABSTRACT:
There is disclosed a data disc on which are recorded at least main text data on which letter or character data are recorded, index data for retrieving the main text data, names of retrievable items, and leading addresses of the indices associated with the names of the retrievable items to enable unification of the retrieving software pieces. There is also disclosed a data retrieving method including displaying the names of retrieving items on the data disc, entering data of retrieving items in dependence upon the displayed names of the retrieving items, retrieving the entered data of the retrieving items on the basis of the index and reading out and displaying the main text data associated with the data of the retrieved items to enable the retrieving software pieces to be unified as well as to enable a variety of application software pieces to be realized.
