Processing hard disk drive (HDD) data track repeatable runout (RRO) compensation data includes, for each read-write head constituent to the HDD, and for each data track on which the read-write head operates, saving RRO compensation data to single-level cell (SLC) area of a NAND memory component, and finalizing the RRO data before processing the next read-write head of the HDD, thereby minimizing the SLC area used. Finalizing the RRO data may include sorting the RRO data for the read-write head in the SLC area, moving the sorted RRO data from the SLC area to triple-level cell (TLC) or other higher-level cell area of the NAND, and then erasing the RRO data from the SLC area to free up that memory space, thereby reducing the risk of wearing out the TLC area.

According to one embodiment, a magnetic disk apparatus includes a magnetic disk, a magnetic head, and a controller. The magnetic disk includes a plurality of tracks. The magnetic head performs read/write from/to the plurality of tracks. The controller controls, in a first case in which, during execution of write to a first track among the plurality of tracks, a position of the magnetic head is displaced from a target position corresponding to the first track toward a second track, and a first distance exceeds a first threshold, write to the second track under a condition different from a condition in a second case in which the first distance is less than the first threshold. The second track is a track different from the first track among the plurality of tracks. The first distance is the distance between the target position and the position of the magnetic head.

An apparatus according to one approach includes an array of skew detection transducers. An array of write transducers is spaced from the array of skew detection transducers along an intended direction of tape travel thereacross. An array of read transducers is aligned with the array of write transducers in the intended direction of tape travel. The apparatus also includes a first actuator configured to operatively exert a force on the array of skew detection transducers for orienting a longitudinal axis of the array of skew detection transducers substantially orthogonal to the actual direction of tape travel across the array of skew detection transducers. A magnetic recording medium according to one approach includes a magnetic recording tape having a longitudinal axis extending between distal ends thereof, the magnetic recording tape having vertical bars written in servo-skew patterns thereof, the vertical bars being oriented perpendicular to the longitudinal axis of the tape.

A processor includes a transmitter to transmit, to a receiver, a differential pair of signals including a positive signal transmitted across a positive conductor and a negative signal transmitted across a negative conductor. A first programmable analog delay circuit is coupled to the positive conductor to provide a first delay to the positive signal and a second programmable analog delay circuit is coupled to the negative conductor to provide a second delay to the negative signal. A controller receives data based on a bit error rate (BER) of the differential pair of signals as measured by a bit error checker of the receiver. In response to determining the BER is less than a threshold BER, the controller stores a first delay value to program the first delay and store a second delay value to program the second delay.

The magnetic tape includes: a non-magnetic support; and a magnetic layer containing a ferromagnetic powder, in which a non-linear component of tape width deformation generated by storage for 10 days in an environment of a temperature of 60° C. and a relative humidity of 20% is 100 nm or less. A magnetic tape cartridge and a magnetic tape apparatus include the magnetic tape.
