Disc with embedded flash memory and disc drive
View Patent ↗A disc has an outer section on which digital media can be recorded and a core in its center in which a flash memory is embedded with the core having a central hole and electrical contacts to the flash memory. A disc drive has a drive spindle that is to extend into the disc core central hole with one of the spindle or spindle hub having electrical contacts to engage with the core electrical contacts so that data can be written into and/or read from the core flash memory by electronic components of the drive.
1. A method comprising:
providing a disc having an outer section on which digital data is recorded and an inner core having a central hole and an alignment tab extending into said central hole, said inner core including a flash memory with at least one electrical contact, said at least one electrical contact extending from said flash memory onto a peripheral wall of said inner core forming said central hole;
engaging said at least one electrical contact of said flash memory with at least one drive electrical contact of a drive spindle of a disc drive, said drive spindle having a vertical slot to accommodate said alignment tab of said inner core; and
while rotating the disc in the disc drive about the drive spindle extending into said central hole of said inner core, performing one of reading data from or writing data to said flash memory via said at least one drive electrical contact of said drive spindle.
2. The method as claimed in claim 1 wherein said at least one drive electrical contact is accessible from an outer periphery of said drive spindle.
3. The method as claimed in claim 1 wherein said at least one electrical contact is on said alignment tab of said inner core, and wherein said at least one drive electrical contact is in said vertical slot of said drive spindle.
4. The method as claimed in claim 1 further comprising, while rotating the disc, simultaneously reading data optically from the outer section of said disc and reading data electrically from the flash memory.
5. The method as claimed in claim 1 , wherein said at least one electrical contact extending from said flash memory onto a peripheral wall of said inner core forming said central hole is a plurality of electrical contacts, and wherein said at least one drive electrical contact of said drive spindle of said disc drive is a plurality of drive electrical contacts.
6. A method comprising:
providing a disc having an outer section on which digital data is recorded and an inner core having a central hole and an alignment tab extending into said central hole, said inner core including a flash memory with at least one electrical contact, said at least one electrical contact extending from said flash memory;
engaging said at least one electrical contact of said flash memory with at least one drive electrical contact of a drive spindle base of a drive spindle of a disc drive, said drive spindle having a vertical slot to accommodate said alignment tab of said inner core and said drive spindle base supporting said disc; and
while rotating the disc in the disc drive about the drive spindle extending into said central hole of said inner core, performing one of reading data from or writing data to said flash memory via said at least one drive electrical contact of said drive spindle base.
7. The method as claimed in claim 6 wherein said at least one electrical contact extending from said flash memory is on said alignment tab of said inner core, and wherein said at least one drive electrical contact of said drive spindle base is in said vertical slot of said drive spindle.
8. The method as claimed in claim 6 further comprising, while rotating the disc, simultaneously reading data optically from the outer section of said disc and reading data electrically from the flash memory.
9. The method as claimed in claim 6 , wherein said at least one electrical contact extending from said flash memory is a plurality of electrical contacts, and wherein said at least one drive electrical contact on said drive spindle base of said drive spindle of said disc drive is a plurality of drive electrical contacts.
