  • Logical expiration of media having embedded non-volatile memory
    Patent number: 6804075
    Abstract: An expiration configuration is encoded into non-volatile memory embedded in media, such as a tape cartridge. The encoded expiration configuration specifies if the media is expired and the action to perform if the media is expired. The action may be performed by an application that reads the encoded expiration configuration or by a media device hosting the media. An expiration data for the media may be stored in the encoded expiration configuration or in an external data record.

  • Method and apparatus to read past EOD marker
    Patent number: 6775087
    Abstract: A data storage device having a read-past-EOD marker flag is described herein. The read-past-EOD marker flag may be stored in a non-volatile memory, such as EEPROM, coupled to the data storage device. In one embodiment, the data storage device is a magnetic tape cartridge. The read-past-EOD marker flag, when set to an “on” position, may enable a magnetic tape drive to read past an EOD marker stored on the magnetic tape.
