Abstract

This invention is a new device which is a small sticky magnetic "donut" that is applied to the back side of the CD. (The side that is painted with the album title...) A new CD player will have the capability to read information from this CD and write information to this sticky on the CD. This way if the CD is played on a different player that also has this feature, the programming of the CD player will be automatic.

Remembering CD options

This invention is a new device which is a small sticky magnetic "donut" that is applied to the back side of the CD. (The side that is painted with the album title...) A new CD player will have the capability to read information from this CD and write information to this sticky on the CD. This way if the CD is played on a different player that also has this feature, the programming of the CD player will be automatic.

Eventually, this magnetic ring will likely be built into the CD, but for existing CDs the magnetic donut would be purchased separately and come with a simple applicator that fits in the hole of the CD to perfectly align the magnetic donut. So all the user needs to do is peel off the back and thread the applicator in the hole and stick the donut on the CD.

Now that the CD has been converted into a hybrid CD, when it is put into the player and the machine is programmed to play the user's favorite tracks, the user can press a button to save these options.

Now when the CD is inserted into the player again, the player will try to read the donut and if it can it will program the CD player and start to play the CD.

This technology could also be used with software install discs as well. The install options could be saved directly on this donut so that if the hard file crashes, the options are stored on the install CD. (In this case the magnetic part of the CD would likely come built into the install CD.)

FIG 1

The figure above shows a compact optical disc with the sticky applied to it. The inner radius of the sticky lines up with the start of the painted surface and extends 1/4 of an inch out. This width allows the sticky to function even if there is a slight misalignment of sticky during application.

FIG 3

Figure 3 shows the layout on disc. For the CD player application the storage requirement can be met with 2 tracks.

The inner track is simply a formatting track used to by the reader to determine that the disc is formatted and can be read. For this purpose this is simply a track of 01010101010101010101010101010101.... With a single occurrence
of ..01011101... where the middle '1' of the ..01110.. marks the start of the track.

The outter track is the track that contains data. This t...
