Claim 11

An information retrieving system comprising: a disk-shaped recording medium, for storing retrievable information data recorded under a predetermined rule, and a retrieving apparatus, including: input means for inputting information via retrieving keys; data reading means for reading out said retrievable information data recorded at a position of said disk-shaped recording medium by moving in a radial direction of said disk-shaped recording medium in accordance with instruction from a control means; memory means for storing a retrievable table comprising index information comprised of index data structured by a tree-structure relation based on said recorded predetermined rule of said retrievable data of said disk-shaped recording medium, placing a first character of said index data at a summit of said tree-structure relation and address information composed of addresses on said disk-shaped recording medium in connection with said retrievable data corresponding to said index information; and, control means for retrieving said retrievable table at each of said retrieving keys, every time each character of inputted information is entered from said input means, and to move said data reading means to said address obtained.

Claim 12

An information retrieving system according to claim 9, wherein said retrievable table is stored in said disk-shaped recording medium and said retrievable table is loaded to said memory means at such time of retrieving information.

Claim 13

An information retrieving method for a retrieving apparatus comprising a disk-shaped recording medium storing retrievable data, and a retrievable table comprising index information comprised of index data structured by a tree-structure relation based on a recorded predetermined rule of the retrievable data of the disk-shaped recording medium, providing a plurality of key inputs for retrieving data on said disk-shaped recording medium, retrieving said retrievable table at each of said retrieving key inputs by one character to obtain an address on said disk-shaped recording medium, and moving a data reading means of said retrieving apparatus at each retrieving key input sequentially to said address to read retrievable data existing in the address on said disk-shaped recording medium.

Claim 14

An information retrieving method for a retrieving apparatus comprising a disk-shaped recording medium storing retrievable data, and a retrievable table comprising index information comprised of index data structured by a tree-structure relation based on a recorded predetermined rule of the retrievable data of the disk-shaped recording medium, providing a plurality of key inputs for retrieving data on said disk-shaped recording medium, retrieving said retrievable table at each of said retrieving key inputs by one character to obtain an address on said disk-shaped recording medium, and moving a data reading means of said retrieving apparatus at each retrieving key input sequentially to said address to read retrievable data existing in the address on said disk-shaped recording medium.

Claim 15

An information retrieving system as in claim 9, wherein said disk-shaped recording medium corresponds to a CD-ROM (compact disk-read-only memory).

Claim 16

An information retrieving system as in claim 9, wherein said input means for inputting information comprises a keyboard.

Claim 17

An information retrieving system as in claim 9, further including a display apparatus for displaying both said inputted information and output data.

Claim 18

An information retrieving system as in claim 9, wherein data corresponding to said inputted information is a telephone number.

Claim 19

An information retrieving system as in claim 14, wherein said display apparatus is a display screen and non-outputted retrieved item numbers are displayed on said screen, in such event that plural retrieved output data exists.

Claim 20

An information retrieving system as in claim 9, further including telephone connecting means for converting telephone number data obtained based on the retrieval result into a dial signal, and connecting said information retrieving system to a telephone set of a corresponding telephone number.

Claim 21

An information retrieving system wherein information arranged by a series of characters in inputted and data corresponding to said inputted information is read out from a disk-shaped recording medium, comprising: a disk-shaped recording medium, and a head which searches for a direction of a recording position of said data on said disk-shaped recording medium, corresponding to said inputted information, every time a character of said series of characters of said inputted information is successively inputted, said head stopping at said recording position of said data upon completion of an entry operation of said inputted information wherein each position sought by said head corresponds to a recording position for that data recorded at a head position taking into consideration that data already inputted corresponding to said information arranged by said character series.

Claim 22

An information retrieving system wherein information arranged by a series of characters in inputted and data corresponding to said inputted information is read out from a disk-shaped recording medium, comprising: a disk-shaped recording medium, and a head which searches for a direction of a recording position of said data on said disk-shaped recording medium, corresponding to said inputted information, every time a character of said series of characters of said inputted information is successively inputted, said head stopping at said recording position of said data upon completion of an entry operation of said inputted information wherein each position sought by said head corresponds to a recording position for that data recorded at a head position taking into consideration that data already inputted corresponding to said information arranged by said character series.
