Abstract
Disclosed herein are methods of using embedded disconnected circuits (EDC) in magnetic storage media to assist in reading data from and writing data to the magnetic storage media. A wireless activation signal is used to activate an EDC in a magnetic storage media. Once activated, the EDC may assist to record data in and/or read data from one or more memory locations of the magnetic storage media.
Claims26
A method of using an embedded disconnected circuit (EDC) to read a storage location of a magnetic storage media, the method comprising:
- a signal generator transmitting a wireless activation signal;
- the EDC receiving the wireless activation signal;
- the EDC determining a contents of the storage location in response to receiving the wireless activation signal;
- and
- the EDC transmitting a read response signal indicating the contents of the storage location.
A method of recording data on a magnetic storage media comprising a first storage location, a first embedded disconnected circuit (EDC) configured to assist in recording first data in the first storage location, a second storage location, and a second EDC configured to assist in recording second data in the second storage location, the method comprising:
- activating the first EDC but not the second EDC;
- while the first EDC is activated and the second EDC is deactivated, recording the first data in the first storage location;
- activating the second EDC but not the first EDC;
- and
- while the second EDC is activated and the first EDC is deactivated, recording the second data in the second storage location.
22-28. (canceled)
A method, comprising:
- activating an embedded disconnected circuit (EDC) of a magnetic storage media;
- and
- recording data in or reading data from a memory location of the magnetic storage media while the EDC is activated.
30-32. (canceled)
A method of recording data on a magnetic storage media comprising a first storage location in a first recording layer, a second storage location in a second recording layer, the first storage location being a closest storage location in the first recording layer to the second storage location, and an embedded disconnected circuit (EDC) disposed adjacent to the second recording layer, the method comprising:
- activating the EDC;
- recording data in the second storage location while the EDC is activated;
- deactivating the EDC;
- and
- recording data in the first storage location while the EDC is deactivated, wherein the recording data in the first storage location does not overwrite the data recorded in the second storage location.
