## Abstract

The present invention relates to a recording/reproducing method, a recording/reproducing apparatus and a recording medium. In the conventional art, there is no method of distinguishing a program recorded on an RE layer by an application on a ROM layer, from a program recorded on the RE layer by a user, on a hybrid disc. The present invention solves a problem as described above by separating a folder in which the application on the ROM layer performs recording, from a folder in which the user performs recording, and retaining information indicating a subject which has performed the recording.

## Claims

### Claim 1

A recording method of recording information on a recording medium including a reproduction-only data layer and a recording/reproduction data layer, the recording method comprising the steps of:
recording an AV stream and management information under a first directory of the recording/reproduction data layer by a program on the reproduction-only data layer, and
recording an AV stream and management information under a second directory of the recording/reproduction data layer by a user,
wherein the first directory and the second directory are independent from each other.

### Claim 2

A recording apparatus for recording information on a recording medium including a reproduction-only data layer and a recording/reproduction data layer, the recording apparatus comprising:
a recording unit in which an AV stream and management information are recorded under a first directory of the recording/reproduction data layer by a program on the reproduction-only data layer; and
a recording unit in which an AV stream and management information are recorded under a second directory of the recording/reproduction data layer by a user,
wherein the first directory and the second directory are independent from each other.

### Claim 3

A reproducing method of reproducing information from a recording medium including a reproduction-only data layer and a recording/reproduction data layer, the reproducing method comprising the steps of:
reproducing an AV stream and management information from under a first directory of the recording/reproduction data layer by a program on the reproduction-only data layer; and
reproducing an AV stream and management information from under a second directory of the recording/reproduction data layer by a user,
wherein the first directory and the second directory are independent from each other.

### Claim 4

A reproducing apparatus for reproducing information from a recording medium including a reproduction-only data layer and a recording/reproduction data layer, the reproducing apparatus comprising:
a reproducing unit in which an AV stream and management information are reproduced from under a first directory of the recording/reproduction data layer by a program on the reproduction-only data layer; and
a reproducing unit in which an AV stream and management information are reproduced from under a second directory of the recording/reproduction data layer by a user,
wherein the first directory and the second directory are independent from each other.

### Claim 5

A recording medium including a reproduction-only data layer and a recording/reproduction data layer, comprising:
on the recording/reproduction data layer, a first directory under which a program on the reproduction-only data layer performs recording, and an AV stream and management information under the first directory; and
on the recording/reproduction data layer, a second directory under which a user performs recording, and an AV stream and management information under the second directory,
wherein the first directory and the second directory are independent from each other.
