Abstract
A data storage device can transition a functional data storage medium into a read only data surface. Data can be written to a data storage medium with a data writer of a transducing head prior to a security threat being identified. A write head of the transducing head is deactivated in response to the security threat by selecting a permanent deactivation mechanism.
Claims20
An apparatus comprising a transducing head comprising a data writer, data reader, and permanent deactivation mechanism, the permanent deactivation mechanism configured to sever an electrical connection to the data writer to permanently deactivate the data writer upon selection by a connected controller in response to a security threat identified by a security module of a controller connected to the transducing head, the data reader remaining operational after the data writer is permanently deactivated.
A method comprising:
- writing data to a data storage medium with a data writer of a transducing head;
- identifying a security threat with a security module of a controller connected to the transducing head;
- deactivating the data writer in response to the security threat by selecting a permanent deactivation mechanism to sever an electrical connection to the data writer;
- and
- reading data from the data storage medium with a data reader of the transducing head.
A method comprising:
- writing data to a data storage medium with a data writer of a transducing head;
- predicting a security threat with a prediction module of a controller connected to the transducing head;
- deactivating the data writer in response to the predicted security threat by selecting a permanent deactivation mechanism to sever an electrical connection to the data writer;
- and
- reading data from the data storage medium with a data reader of the transducing head.
