Another embodiment includes a system comprising: a CD reader capable of reading one or more identifiers that include model number, product number, and color of a CD. One other embodiment includes a method for creating a compilation of digital data on a medium such as a CD, comprising: providing access to a database wherein songs are selectable from the database to make a compilation; calculating royalty and other costs to each song; calculating royalty and other costs for the compilation; downloading songs from the database; and recording the compilation of songs on a CD using the method described above.
Detailed Description Methods and apparatus for preventing unauthorized copying of CD's, DVD's and other media capable of recording digital data such as audio, video, software, photo applications, video games and other content capable of being converted to digital data are described herein. In the following description, numerous specific details are set forth. However, it is understood that embodiments of the invention may be practiced without these specific details. In other instances, well-known circuits, structures, and techniques have not been shown in detail in order to avoid obscuring the understanding of this description. Note that in the description, references to "one embodiment" or "an embodiment" mean that the feature being referred to is included in at least one embodiment of the invention. Further, separate references to "one embodiment" in this description do not necessarily refer to the same embodiment; however,
neither are such embodiments mutually exclusive, unless so stated and except as will be readily apparent to those of ordinary skill in the art. Thus, the invention described herein may include any variety of combinations and/or integrations of the embodiments described herein. Moreover, in this description, the phrase "exemplary embodiment" means that the embodiment being referred to serves as an example or illustration. Definitions: "Absolute Time in Pregroove, ATIP", refers to a part of the disc that specifies characteristics of the disc, for example, number of blocks and manufacturer information. On a pressed disc, the timing information that is necessary to control the disc's rate of spin is included in each CD sector as data. But for a blank disc, the CD recorder must have some way to guide the recording laser and control the speed of the blank disc as it is being recorded. That is where the "wobble" in wobbled pregroove comes in. The wobbled pregroove provides tracking and timing information for the recording laser. The wobble is a slight sinusoidal wave that has an "excursion" of .03mm from the center of the track path... The wobble guides the recorder and provides timing information. This information is called Absolute Time In Pregroove (ATIP). It ensures that data is recorded at a constant rate. The resulting data track obliterates the wobbled pregroove, leaving recorded data in its place. An "optical disc", as used herein, refers to an electronic data storage medium that can be written to and read using a low-powered laser beam. A laser read the dots, and the data was converted to an electrical signal, and finally to audio or visual output. Optical disc formats include CD formats, and DVD formats. A"CD-ROM (Compact Disc, read-only-memory)", as used herein, refers to an adaptation of the CD that is designed to store computer data in the form of text and graphics, as well as hi-fi stereo sound. Format of the CD-ROM is the same as for audio CDs: a standard CD is 120 mm (4.75 inches) in diameter and 1.2 mm (0.05 inches) thick and is composed of a polycarbonate plastic substrate (underlayer - this is the main body of the disc), one or more thin reflective metal (usually aluminum) layers, and a lacquer coating.
One system embodiment of the invention described herein includes one or more optical discs that have been developed for preventing copyright infringement of songs. In particular, the discs contain indicia that impart a particular, and, for some embodiments, a unique identity to the discs. One type of optical disc, SecurOQ, has been developed by GE Plastics, located in Pittsfield, Mass. To be operational, the SecurOQ disk must be validated when the disc is installed in a disc drive. In one embodiment, the disc drive is a CD-RW optical disc drive. In one system embodiment, the disk is validated using a 52X CD- R RW optical disk drive. One type of validation device is manufactured by Plextor. Plextor is owned by Shinano Kenshi, Co., Ltd of Japan. Plextor has offices in Fremont, CA. In one embodiment, the system also includes an optical disc writer. One optical disc writer is a Plextor drive, Plextor Premium 52/32/52. The optical disc writer includes an 8 MB buffer for software integration. While a Plextor drive is described, it is understood that other drives are usable in embodiments of the invention described herein. At least three systems, shown schematically in FIG. 1 are usable for optical disk validation, either singly or in combination. A first system performs Absolute Time in Pregroove, ATIP, validation. A second system performs color verification, wherein a disc color must match specific, and in some instances, standardized, resin color that is used in disc construction. A third system performs UV verification. Other system embodiments perform validation using one, two or all of the validations of ATIP, color verification, and UV verification. For some embodiments, ATIP validation is performed first, color verification is performed second and UN verification is performed third. The system embodiments perform verification in accordance with method embodiments described herein. A flow chart for one method embodiment is illustrated at 10 in Figure 1. For this embodiment, a disc is inserted into a CD writer, such as a Plextor Premium writer modified for verification method embodiments of the invention. The model and product number of the disc is checked by a disc reader. In one embodiment, if there is no
match of approved model and product number, the process is terminated. If there is a match of model and product number, a link is activated that allows the CD bum process to proceed. In another embodiment, if there is no match of approved model and product number, the disc is further checked for indications that it is an approved, SecureOG disc. An F/W Table is automatically checked for possible disc upgrade. If data indicates that the disc is an approved disc, a link allows the CD bum to proceed. While CD is described, it is understood that the system and method are usable for optical discs generally and for media capable of receiving digital content by a process such as burning. In another embodiment, if there is no match of approved model and product number, the CD writer reads the color of the disc. If there is no color match, the process is terminated, hi another embodiment, the CD writer reads the color of the disc without a prior check of approved model and product number. If there is a color match, the disc is verified with UV verification. If the UV verification confirms that the disc is a secure disc, a link allows the CD bum to proceed. If the UV verification does not verify the disc, the process is terminated. In one embodiment, the system of the invention described herein includes a CD reader capable of reading identifying indicia on a disc that includes model and product number and color of the disc. The system also includes a CD reader that is capable of performing UV verification. In another embodiment, the CD reader is capable of reading one or more of model and product number, color of the disc, and is capable of performing UV verification. For some embodiments, the system includes more than one CD reader. Some system embodiments also include one or more links that allow CD burning, upon actuation. The links are actuated when model and product number of a CD are verified by the CD reader, a color of the CD matches a standard color, or upon UV verification, or when more than one of these events occur. While CD reader is described herein, it is understood that optical readers having functionality described herein are suitable for use. Another system embodiment of the invention, illustrated at 100 in FIG. 2, includes a portal, such as an internet portal, for receiving content from preselected content providers. The content includes one or more of digital
music, album covers, and information about artists creating the music. For other embodiments, the content includes video images or other multi-media that is recordable on an optical disc, such as a CD. Other digital content includes DVD's, digital photo applications, video games, and software. While specific digital content embodiments are described, it is understood that other digital content embodiments are usable in the system and method embodiments described herein. In one embodiment, content is stored on a central server 20 and mass storage 22. For some embodiments, content is licensed from other providers 24 and 26. For other embodiments, the content is unbound 28. The content is selected and downloaded from the internet to a server 12. The content is directed from the server 12 to mass storage 14 or to a CD recorder and optional label printer 16. The content is selected as a result of consumer input at the kiosks 18. The specific functions that occur at each element in the system are described in FIG. 3. One method embodiment of the invention, illustrated in FIGs. 4 and 5, permits a consumer to search for music by artist, album, or song. This search is done, in one embodiment at a kiosk. For other embodiments, searching is performed using a device such as a personal digital assistant, PDA, or other handheld device. In one embodiment, a consumer enters a store and obtains a PDA. The consumer uses the PDA to collect tags identifying digital music, or to collect the digital music as the consumer moves about the store. When the consumer has compiled the digital music desired, the PDA is inserted into a docking station, where the data is uploaded to the server 12 for recording onto a CD. In one embodiment, the CD is a SecurOQ or other CD capable of being validated. The CD is validated using the system described above and shown in FIG. 1. Consumers may search for not only artists, albums or specific digital music, but also, if desired, related artists and related albums. If a consumer selects a related artist, the kiosk or PDA displays the album cover, metadata and song list of the related artist. The consumer has an option of listening to a sample of the music with the kiosk. If the consumer selects a song for recording on a CD, a check is made on whether the song is licensed for burning, and the song's availability locally. The consumer is warned of additional download
time, in one embodiment. The song is added to the recording list. In one embodiment, the price of the song is stored. The recording list is displayed to the consumer, along with the number of discs for recording and the price per song and cumulative price. The consumer has a final opportunity to play a sample of songs from the recording or to a "bum" list before the disc or discs containing the selected songs are created. The consumer has an option to remove a song. If this option is selected, the song is deleted from the list and costs are re-calculated. The local availability of each song in a recording list, also referred to as a "bum" list, is determined. If the song is not locally available, a check is made of the other accessible databases. Once the song is located, it is downloaded to the local server 12. If necessary, the song file is decrypted and recorded onto the CD. The procedure is repeated for the next song and continues until all of the songs on the list have been downloaded and decrypted; The songs on the list are then recorded on a CD. A CD label is printed.
The label includes all of the songs on the CD and other information, if desired. A check is made to determine whether the CD creation is successful. If the creation is found to be unsuccessful, the recording process is repeated. If the creation is found to be successful, the songs are recorded for royalty reporting. In one embodiment, a report of cost, including royalties, is prepared and sent to a retail sales system. Another disc is presented for song recording. Another embodiment of the invention includes a security system. The security system is usable with the CD recording system embodiment described in FIG. 1 and above. The security system marks the disc recording medium with a unique tag, such as the color-based tag described for the SecurOG CD, described above. For some embodiments, the unique tag is a number that is mechanically applied to the recording media. For other embodiments, the unique tag is radio frequency identification, RFID, that includes multiple pieces of data. The unique tag is added to the compilation database of the system embodiments so that an identified consumer and song list is associated with the unique tag. This information is, optionally, transmitted to the owners of the song databases and owner of the store wherein the transaction occurs. In one embodiment, if the consumer or another party tries to copy the compilation, the tag will copy too. If a new tag, such as a serial number or a
color or both, is embedded in the disc, the presence of the old tag in the database will block recording on the new disc. If the old tag is associated not just with the compilation but with each song on the disc, the presence of the old tag blocks the song's recording on the new disc. Thus, one method for preventing unauthorized copying of a song or other content capable of being burned into or onto a CD includes inserting a disc media into a CD reader. The CD reader reads at least one or more of the model and product number of the disc media, for some embodiments and other identifying indicia or identifying tags for other embodiments. The model and product number, other identifying indicia or identifying tags are compared to a database of approved model and product numbers, other identifying indicia or other identifying tags. The CD bum proceeds if the identifying indicia on the CD matches the identifying indicia in the database. The CD bum is terminated if the identifying indicia on the CD does not match any of the identifying indicia in the database. In addition to model numbers and product numbers, approved indicia includes approved colors of the recording media. Approved indicia also includes indicia readable upon application of ultraviolet light or RFLD. Having described and illustrated the principles of the invention in particular embodiments thereof, it should be apparent that the invention can be modified in arrangement and detail without departing from such principles.
