Abstract: Identifying recording disk defects in a data storage device such as a hard disk drive (HDD), for which disk defects are not previously identified, includes responsive to a first user data write request to a particular storage area of a disk medium, writing the user data to the particular storage area, reading the written user data from the particular storage area, and verifying the integrity of the user data read from the particular storage area. Upon passing, a second user data write request to the same particular storage area can be fulfilled without again reading and verifying. Upon failing, the particular storage area is marked as defective and the user data is written to a different storage area. This procedure can be repeated in response to each initial user write request to each storage area of each disk medium, foregoing the need for disk surface scanning during manufacturing.

Abstract: Technology is disclosed for a current source for reading a memory cell having a threshold switching selector. The current source may be operated in a first mode when turning on the threshold switching selector and in a second mode when sensing a voltage across the memory cell. The first mode may allow the use of the full range of the power supply voltage, which provides sufficient voltage across the memory cell to turn on the threshold switching selector. In the second mode the magnitude of the read current is less dependent on the voltage across the memory cell. The second mode therefore provides for accurate sensing of the memory cell. The first mode may also be used when writing the memory cell, which provides sufficient voltage across the memory cell to write the memory cell.
