IEEE Transactions on Magnetics, 2019

Heat-assisted magnetic recording (HAMR) is the next-generation hard disk drive technology which enables continued and significant areal density growth. There are currently three write architectures for the layout of tracks in hard disk drives: conventional magnetic recording (CMR), shingled magnetic recording (SMR), and interlaced magnetic recording (IMR). The read-back architecture multiple-sensor magnetic recording (MSMR) can be combined with the three ...

  • Areal Density Comparison Between Conventional, Shingled, and Interlaced Heat-Assisted Magnetic Recording With Multiple Sensor Magnetic Recording

    Heat-assisted magnetic recording (HAMR) is the next-generation hard disk drive technology which enables continued and significant areal density growth. There are currently three write architectures for the layout of tracks in hard disk drives: conventional magnetic recording (CMR), shingled magnetic recording (SMR), and interlaced magnetic recording (IMR). The read-back architecture multiple-sensor magnetic recording (MSMR) can be combined with the three different write architectures to increase the areal density by using two or more readers to read-back the same track. In this paper, we compare the areal density capability of HAMR CMR, HAMR SMR, and HAMR IMR combined with read-back with one reader, MSMR with two readers, and MSMR with three readers.

  • Fabrication and Magnetic Properties of Nonmagnetic Ion Implanted Magnetic Recording Films for Bit-Patterned Media

    We have investigated the magnetic M-H loop characteristics of CoCrPt-SiO2 perpendicular recording media as influenced by nonmagnetic ion implantations. We have also developed patterned media via ion implantation using a convenient polymer nanomask approach for local control of coercivity of magnetically hard [Co/Pd]_n_ multilayer film with a [Co 0.3 nm \Pd 0.8 nm] 8/Pd 3 nm/Ta 3 nm layer structure. The CoCrPt-SiO2 magnetic layer having perpendicular magnetic anisotropy is sputter deposited on a flat substrate. The [Co/Pd] _n_ multilayer film with vertical magnetic anisotropy is deposited and the regions corresponding to the magnetic recording bit islands are coated with polymer islands using a nanoimprinting technique. Subsequent ion implantation allows patterned penetration of implanted ions into the [Co/Pd]_n_ multilayer film, thus creating magnetically isolated bit island geometry while maintaining the overall flat geometry of the patterned media.

  • Optimization of Magnetic Read Widths in Two-Dimensional Magnetic Recording Based on Micromagnetic Simulations

    Optimization of magnetic read widths (MRWs) and reader positions in two- dimensional magnetic recording (TDMR) is explored in order to maximize an areal density (AD) gain over shingled magnetic recording (SMR). The optimization is based on micromagnetic waveforms from 511-bit maximal-length pseudorandom binary sequence (PRBS) patterns. The identical MRWs for two readers are initially considered and the best reader offset is found in order to achieve the largest AD gain. Given the best reader offset, the MRWs for the two readers are changed to further enhance the AD gain. A software channel is utilized to identify the major contribution of the TDMR AD gain.

  • Definition of an Areal Density Metric for Magnetic Recording Systems

    The areal density capability (ADC) of a magnetic recording disk drive is highly dependent on the application or market segment. In this paper, we define a new areal density metric, which represents what areal density is possible under ideal recording conditions. This proposed areal density metric enables the industry to standardize and compare the ADC of magnetic recording disk drives across various recording technologies independent of market segment. We demonstrate the performance of experimental 2-D magnetic recording and heat assisted magnetic recording technology components measured using the proposed areal density metric.

  • Perspectives of magnetic recording system at 10 Tb/in2

    Due to the superparamagnetism, the configuration of magnetic recording system has to be changed in order to enhance the writing capability or to reduce the number of grains per bit. The next target of magnetic recording research is to enable HDD technologies at the areal density of 10 Tb/in2. This work studies the feasibility and the requirement to implement the magnetic recording system at 10 Tb/in2. From the analysis of two possible approaches: the energy assisted magnetic recording (EAMR) on granular media and the bit patterned media (BPM) with EAMR, the simulation based virtual design of magnetic recording system at 10 Tb/in2 is proposed.

  • Numerical modeling of heat assisted magnetic recording system

    Heat assisted magnetic recording (HAMR) is envisioned as the next technology for boosting the recording densities. In HAMR, a localized optical field is used to locally heat the magnetic recording media layer, thus reducing the thermal stability and allowing recording at sufficiently weak magnetic fields. After cooling down, the recording layer restores the original high thermal stability. From the simulation point of view HAMR requires integrated modeling approaches, including magnetics, optics, heat transport, and electromagnetics.

  • Geometrically Planar Ion-Implant Patterned Magnetic Recording Media Using Block Copolymer Aided Gold Nanoisland Masks

    We have developed patterned media via ion implantation using Au nano mask approach for local control of coercivity of magnetically hard [Co/Pd]n multilayer film. Au nano-islands produced through a di-block copolymer templated technique is used as the mask for ion implantation. The sputter deposited [Co 0.3 nm/Pd 0.8 nm]8/Pd 3 nm/Ta 3 nm multilayer film having vertical magnetic anisotropy is coated with a diblock copolymer layer, two phase decomposed into vertically pored nanostructure, then chemically processed to nucleate gold nanoislands corresponding to the diblock copolymer nanostructures. Subsequent nitrogen (N) ion implantation, using these Au islands as implantation-blocking masks, allows a patterned penetration of implanted ions into unmasked portion of the [Co/Pd]n multilayer film, thus creating invisible but magnetically isolated bit island geometry while maintaining the overall flat configuration of the patterned media.

  • Dynamic switching in magnetic recording

    In this paper, we discuss consequences for a variety of recording configurations such as CP recording, TP recording, longitudinal recording in case of dynamic switching in magnetic recording.

  • Polar Code Design for Ultra-High Density Magnetic Recording Channels

    A simple Polar code optimization algorithm for a two-dimensional (2D) inter- symbol interference (ISI) channel is proposed for ultra-high density magnetic recording, such as bit-patterned magnetic recording (BPMR) and two-dimensional magnetic recording (TDMR), by exploiting the mutual information (MI) between input and output of 2D detector (2D-DET) to re-model the log-likelihood ratio (LLR) messages as Gaussian distribution. The new method, which captures the error characteristics of magnetic recording, builds a bridge of Polar code optimization between the 2D-ISI channels and AWGN channels. The “gap” due to the 2D-ISI, can be computed by the new modeling, so the classic polar code optimization techniques previously developed for the AWGN channel that are not effective can be re-used in 2D-ISI channels.

  • Four-Reader Array Detection for Two-Dimensional Magnetic Recording

    Two-dimensional magnetic recording is a promising technology to achieve magnetic recording areal density of 10 Tb/in2. But it suffers severe two- dimensional intersymbol interference (2-D ISI). We propose a novel detection architecture which uses a four-reader array to retrieve the recording data. Simulation results show that the proposed approach outperforms both the conventional single reader detection and three-reader array detection.
