## Abstract

A non-transitory computer-readable medium having embodied thereon a program for implementing functions of managing a recording medium in an electronic device, includes a recording medium management module that includes: an acquisition module configured to acquire an upper limit to the number of recording media registered in the electronic device; and a registering module configured to register the recording medium in which the program is installed in the electronic device such that the acquired upper limit is not exceeded. The recording medium management module may link date and time information to a recording medium identifier identifying the recording medium in which the program is installed, and register the information and the identifier as linked in a management database used to manage the recording medium.

## Claims

### Claim 1

A non-transitory computer-readable medium having embodied thereon a program for implementing functions of managing a recording medium in an electronic device, the program comprising a recording medium management module that comprises:
an acquisition module configured to acquire an upper limit to the number of recording media registered in the electronic device; and
a registering module configured to register a recording medium in which the program is installed in the electronic device such that the acquired upper limit is not exceeded.

### Claim 2 (depends on 1)

The non-transitory computer-readable recording medium according to claim 1,
wherein the recording medium management module further comprises a linking module configured to link date and time information to a recording medium identifier identifying the recording medium in which the program is installed, and configured to register the information and the identifier as linked in a management database used to manage the recording medium.

### Claim 3 (depends on 2)

The non-transitory computer-readable recording medium according to claim 2,
wherein the recording medium management module further comprises an unregistration module configured to unregister the recording medium registered in the management database, and
wherein, if the number of recording media registered in the management database reaches the acquired upper limit, the unregistration module selects a recording media candidate to be unregistered from the management database before registering a recording medium, by referring to the date and time information registered in the management database.

### Claim 4 (depends on 2)

The non-transitory computer-readable recording medium according to claim 2, further comprising an area creation module configured to create a data storage area in a recording medium,
wherein the date and time information indicates date and time of when the area creation module created a data storage area in the recording medium.

### Claim 5 (depends on 2)

The non-transitory computer-readable recording medium according to claim 2, further comprising a loopback module configured to publish the data storage area created by the area creation module as an independent recording medium,
wherein the recording medium management module further comprises:
a registration information updating module configured to link, when the data in the recording medium published by the loopback module is updated, the recording medium identifier of the recording medium to date and time information indicating date and time of when the data had been updated, and configured to register the identifier and the information as linked in the management database.

### Claim 6 (depends on 2)

The non-transitory computer-readable recording medium according to claim 2,
wherein the recording medium further stores an electronic device identifier identifying the electronic device that installed the program in the recording medium, and
wherein the recording medium management module suspends, if the electronic device identifier stored in the recording medium is different from the electronic device identifier of the electronic device executing the program, registration of the recording medium in the management database.

### Claim 7

A method of managing a recording medium executed by a processor of an electronic device, comprising:
acquiring an upper limit to the number of recording media registered in the electronic device; and
registering a recording medium in which a designated application program is installed in the electronic device such that the acquired upper limit is not exceeded.

### Claim 8

An electronic device comprising:
a management database used to manage a recording medium in which a designated application program is installed; and
an application execution unit configured to read the application program from the recording medium and to execute the application program,
wherein the application program executed by the application execution unit registers the recording medium in which the application program is installed in the management database such that a predetermined upper limit to the number of recording media registered in the management database is not exceeded.

### Claim 9

An electronic device comprising:
a management database used to manage a recording medium in which a designated application program is installed such that a predetermined number of recording media is not exceeded; and
a database access unit configured to access the management database,
wherein the database access unit links date and time information to a recording medium identifier identifying the recording medium in which the application program is installed, and registers the information and the identifier as linked in the management database.
