Description

Limited-use recordable optical disc and method to limit its use.

Object of the invention

The present invention relates to a disk recordable, compact or DVD optical, which has been especially Designed for data recording.

The object of the invention is to provide a physical media that limits the type of files that can be recorded in it, so as to prevent the recording in it of audio and / or video files, from which rights of Author.

Background of the invention

Nowadays the use of discs is habitual optical (CD's or DVD's) virgins to make recordings of files, both data and music and / or video.

So far, virgin optical discs existing in the market comprise a surface that allows perform digital recording, using recorders installed in personal computers or integrated into other devices electronic devices intended for this purpose, for storage and later reproduction.

These types of devices incorporate origin, on the aforementioned recordable surface a pre-track which may contain data concerning the product (serial number, date, manufacturer code, etc.), can be done subsequently and by the buyer or user of the virgin disk the recording of digital information in successive sessions.

The problem presented by this type of devices is that the user or buyer of the compact disc Recordable can perform recording on the same music copies and / or video from which they derive copyright, either by copying a original disc or downloading them from Internet®.

Once the optical disc has been recorded, it can reproduce on those conventional equipment used at the level domestic.

This use or use of optical discs recordable, in addition to being able to constitute a violation of rights of author, supposes significant economic losses for the record industries that are noticeably diminished the sales of original records.

For this purpose, the applicant himself is the holder of the invention patent 0.200.302.130 "Limited-use recordable compact disc and method of limiting the use thereof" in which a limited-use recordable compact disc is described, in which said multisession disc incorporates a first session recorded at source, with any type of content, so that this support allows subsequent sessions to be recorded by any computer equipment, but which, due to the special particularity of the domestic audio or video players, which only recognize standardized formats and recorded in a single session, these devices will only access the session made at the source and will not be able to reproduce the audio and / or video recorded by the user in sessions
later.

The problem with this device is which does not preclude the recording of audio and / or video, but its reproduction through it in household appliances such as Stereo systems, audio compact disc players (CD) and video (DVD), so that the reproduction of said files It is still possible through computer equipment.

Description of the invention

The limited-use recordable optical disc that the proposed invention resolves in a fully satisfactory manner the problematic previously exposed in the different aspects commented, providing data recording support that it makes it impossible to record audio and / or video files in the same.

To do this, and more specifically, the disk recordable optical that is recommended incorporates a first track prerecorded that contains a self-executing program recording of said support, as well as a track reserved for the recording of files other than audio and / or video, reserving by  Finally, a small free space to finish the recording of the device.

The self-executing program allows the user to record through a simple interface, based on dragging or pasting files from any folder in the system to the reserved space, with the special feature that the disk is limited to a second and only session to which the user You can access to record the files on the mentioned track reserved.

According to another of the characteristics of the invention, said program incorporates a filter that prevents recording of audio and / or video tracks, as well as files of playable content (mp3, wav, wma, ogg ...)

This first filtering phase makes it impossible to audio or video playback on any home player such as music chains, compact disc players or DVD However, certain users record audio files or "camouflaged" video within other files, or simply changing the extension, so that once recorded and introduced into the computer, it is necessary that they be subsequently "descamuflados" to be reproduced. This practice it only allows to use said support as a means of storage.

In order to avoid such practice, the application introduced in the prerecorded track incorporates a second phase of filtering in which it is verified that the extensions of said files match the type of file they accompany, verifying the format or file headers, so that The filtering process is significantly more effective.

Also, if you try to use any recording application other than prerecorded in the first track of the disc, this when accessing it, will interpret that it is a disc with two sessions, a first session in which hosts the aforementioned application, and a second session, "reserved", so that for recording purposes, for that program the disc Optical has no free space in which to record files.

Finally, it should be noted that the application prerecorded on the first track of the optical disc will only allow recording of a single session, so that once introduced previously filtered files, this application will handle that the corresponding recording device ends the disk, canceling the remaining unused disk space on that disk session, and the content being recorded in it accessible from Any computer equipment.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of said description, a drawing where with character illustrative and not limiting, a representation is shown schematic of the internal structure of a recordable optical disc of limited use made in accordance with the purpose of this invention.

Preferred Embodiment of the Invention

In view of the review figure you can be observed as the recordable optical disk of limited use (1) object of the invention incorporates a first track (2) prerecorded in factory, with a self-executing application for data recording to disk (1), which occupies a small space of the disk compared to its total capacity, of order of about 22 Mbytes or what is the same, which is in an approximate range of between 35 and 50 seconds.

Said disk (1) incorporates a second session (3) with virtually all remaining free space, except for the usual 600 bytes (4) needed to finish the disk.

The second session (3), is reserved, so that you can only access data recording on it through the auto-bootable application incorporated in the first track (2) of the disc (1).

As mentioned above, said application incorporates a filtering process that makes it impossible to recording to disc (1) of any type of audio file and / or video that wants to be introduced, avoiding the violation of copyright thereof.
