A junction has been developed for hybrid bubble memory devices using ion-implanted tracks for high density data storage and Permalloy tracks for write and read functions. An 18- mu m diameter Permalloy corner pattern is used. Both the tapered ion-imp

Bloch Line (BL) pair propagation using a field-access scheme has been investigated in the straight pair of stripe domains stabilized around completely etched grooves. Potential wells to define the bit position for the BL pairs were produced by the st

In order to analyze the direct thermomagnetic overwrite process, the domain wall energy, saturation induction, and coercivity for TbFeCo films were measured at high temperatures at which the recorded domains are formed. The domain wall energy was det

A design for a dual gate which has both pseudoswap and block-replicate functions for 16-Mb ion-implanted bubble memory devices has been proposed and shown by Sato et al. (1987) to reduce the operation current-pulse amplitude. The dual gate is compose

Hybrid bubble memory devices have been proposed and operated with the memory density of 4 Mbit/cm2. In the hybrid bubble memory devices, minor loops are composed of ion-implanted tracks with 4-µm period, and major lines and functional parts includin

Junctions between Permalloy and ion-implanted tracks for high-density hybrid bubble memory devices (>or=16 Mb/cm/sup 2/) using 0.5- mu m-diameter bubbles have been investigated at a 100-kHz drive field. The conventional junctions developed for 4-Mb/c

A fabrication process for ion-implanted and Permalloy hybrid bubble memory devices has been developed. The mask patterns of polyimide (PIQ) for ion-implanted tracks are fabricated using a tri-level resist process where the top imaging resists are del

The ion-implanted propagation tracks with contiguous disk patterns (CD tracks) have been confirmed to be better for high density propagation tracks (≥ 16 Mbit/cm2) than those with snake patterns (snake tracks), because of less interactions between

The characteristics of junctions between ion-implanted and Permalloy tracks are described for hybrid bubble memory devices. It has been found that the junctions which have a sharply formed edge of the ion-implanted layer have a problem in reproducibi

A new junction for the swap-gate side using the corner-Permalloy pattern in hybrid bubble memory devices has been designed and characterized. The design is based on the corner-type junction for the replicate-gate side and the conventional swap gate.
